Every trainee in this game tracks affection through four separate systems — chat topics, holidays, discussion choices, and dates — and most players waste weeks picking the wrong ones because nothing in the UI tells you which options actually move the needle. This guide breaks down the exact +2/+1/+0 values for every trainee and key character, so you can stop guessing and start planning your schedule around what each person actually responds to.
The core idea here is simple: affection isn’t random. Every dialogue option, gift, and date location has a fixed value baked into the game’s data. Once you know those values, hitting 3 hearts on any character becomes a matter of repetition, not luck.
Overview: Trainee Categories and Affection System
Trainees split into three specialties: Vocal (Ye-jin, Yuna, Ai), Dance (Gita, Luna, Minji), and Charm (Hana, Yue). Each one sits in a fixed location — you’ll always find Yuna at the Cafe, Minji at the Recording Studio, and so on. No wandering required, just show up.
Hearts unlock in tiers, and the rewards scale predictably:
| Hearts | Reward |
|---|---|
| 1 | New schedule or training unlocked |
| 2 | +5% stat bonus (sometimes applies to all members, not just the trainee) |
| 3 | +3% income bonus for related schedules |
Key characters — Juwon, Maya, Mr. Dae, Cherry, Go, Taehyung, Eunha, Sungho, Mr. Hoon, and Mr. Woo — work differently. Gifting them grants global stat bonuses rather than trainee-specific ones, and their heart tiers unlock things like Fame boosts, Funds, or entirely new career schedules.
Vocal Trainees: Ye-jin, Yuna, Ai
Ye-jin (Manager’s Office) responds best to Jokes, Sports, Local Events, Compliments, Music Charts, Festival Lineups, K-pop Animation, New Albums, and New Group Members — all +2. Skip Gossip, Weather, Private Topics, Brand Collaborations, and Dating Rumors; they do nothing. Send her to Jeju Island for the holiday bonus, not Tokyo. For discussions, Team Concept and Songs & Singing both hit +2. On dates, Beach, Cafe, Cinema, Amusement Park, and Performance Venue all give +2. Best gift: Guitar (+1 affection, +100 Singing).
Yuna (Cafe) likes Jokes, Weather, Local Events, Compliments, Festival Lineups, K-pop Animation, New Albums, New Group Members, and Dating Rumors. Her Jeju Island holiday gives zero, so don’t bother. Work Performance, Group Performance, and Songs & Singing discussions all land +2. For dates, go Mountain, Restaurant, Museum, Performance Venue, or Seoul Forest Park. Her top gift is Over-ear Headphones, +1 affection and +100 Singing.
Ai (Backstage) favors Jokes, Weather, Local Events, Sports, Compliments, Music Charts, Festival Lineups, K-pop Animation, and New Albums. Unlike the others, her holiday pick is Tokyo, +2. Work Performance and Songs & Singing discussions both score +2. Beach, Restaurant, Performance Venue, Salon/Spa, and Seoul Forest Park are her strongest date spots. Best gift: Microphone, +1 affection and +100 Singing.
Dance Trainees: Gita, Luna, Minji
Gita (Cafe) is easy to please — Jokes, Gossip, Sports, Local Events, Compliments, Festival Lineups, K-pop Animation, New Albums, New Group Members, and Brand Collaborations all give +2. Both Jeju Island and Tokyo holidays work for her, unusual among the trainees. Group Performance and Dance & Choreography discussions hit +2. Date-wise, Mountain, Cinema, Amusement Park, Shopping Mall, and Seoul Forest Park top the list. Her best gift is K-pop Album, +1 affection and a huge +100 Singing.
Luna (Shopping Area) responds to Jokes, Gossip, Local Events, Sports, Compliments, Festival Lineups, K-pop Animation, New Albums, New Group Members, and Dating Rumors. None of her holiday options (Jeju Island, Tokyo, New York) give any bonus, so don’t waste a trip planning around her. Work Performance, Group Performance, and Dance & Choreography discussions all score +2. For dates, Mountain, Museum, Performance Venue, Seoul Forest Park, and Shopping Mall are the picks. Headphones, Guitar, and Microphone all tie as her best gifts at +1 affection and +70 Singing each.
Minji (Recording Studio) likes Jokes, Weather, Gossip, Local Events, Compliments, Festival Lineups, K-pop Animation, New Albums, Brand Collaborations, and Dating Rumors. Busan gives nothing for her holiday slot — only Jeju Island scores +2. Fashion & Style and Dance & Choreography discussions both hit +2. Dates should go Beach, Cafe, Amusement Park, Cinema, or Salon/Spa. Her best gift is K-pop Album, +1 affection and +70 Singing.
Charm Trainees: Hana, Yue
Hana (Shopping Area) favors Jokes, Gossip, Local Events, Music Charts, Festival Lineups, K-pop Animation, New Albums, New Group Members, and Brand Collaborations. Her holiday preferences are picky — Busan and Jeju Island give nothing, but New York and Tokyo both hit +2. Team Concept and Fashion & Style discussions score +2. Best dates: Restaurant, Cafe, Amusement Park, Shopping Mall, Salon/Spa. Notably, none of Hana’s gifts push affection above +0, though several still give +50 Singing — treat gifting her as a stat play, not a heart-farming strategy.
Yue (Manager’s Office) likes Jokes, Weather, Local Events, Festival Lineups, K-pop Animation, New Albums, New Group Members, and Brand Collaborations. She’s the pickiest on holidays: Tokyo, Busan, and Jeju Island all give zero, while New York, Nami Island, and Bali each hit +2. Team Concept and Fashion & Style discussions score +2. Dates work best at Mountain, Beach, Restaurant, Cafe, or Museum. Her top gift is K-pop Album, +1 affection and +100 Singing — matching Ye-jin’s best-in-class gift value.
Key Characters: Juwon, Maya, Mr. Dae, Cherry, Go, Taehyung, Eunha, Sungho, Mr. Hoon, Mr. Woo
These ten don’t follow the trainee chat/discussion system — their affection comes almost entirely from gifts and dates, and their heart rewards tend to be economic or career-based rather than stat percentages.
| Character | Location | 1 Heart | 2 Hearts | 3 Hearts |
|---|---|---|---|---|
| Juwon | Bar | Radio DJ schedule | Fame +50 | Funds +1000 |
| Maya | Dance Practice Room | Fame +200, Singing +10% | Runway Model schedule | Reality Show Guest schedule |
| Mr. Dae | Backstage | Movie Lead casting | Funds +546, Fame +250 | Movie Lead schedule |
| Cherry | Recording Studio | Bar DJ schedule | Fame +10%, Singing +15% | TV Commercial Star schedule |
| Go | Dance Practice Room | Brand Ambassador schedule | Singing +15%, Charm +10% | Luxury Brand Ambassador schedule |
| Taehyung | Recording Studio | Harmony schedule | Funds +500 | Funds +1000 |
| Eunha | Dance Practice Room | Backup Dancer schedule | Funds +750 | Funds +1000 |
| Sungho | Backstage | Backup Dancer schedule | Funds +750 | Funds +1000 |
| Mr. Hoon | Cafe | Drama Lead casting | Charm +10, Fame +20 | Drama Lead schedule |
| Mr. Woo | Bar | No interface available | — | — |
Maya’s line is the strongest early pickup — Fame +200 and a flat +10% Singing boost from just 1 heart is worth chasing before anything else on this list. Her best gifts are Over-ear Headphones and K-pop Album, both +1 affection and +30 Singing.
For dates, most of these characters cluster around Bar, Beach, Mountain, and Performance Venue as +2 locations, though the exact combination varies. Juwon and Sungho both favor Bar, Beach, Amusement Park, and Salon/Spa. Mr. Dae and Mr. Woo both prefer Mountain, Restaurant, Museum — a useful overlap if you’re running double dates on the same day.
Mr. Hoon’s date preferences haven’t been logged yet in current data, and Mr. Woo appears to have no heart-unlock interface at all — gifting him seems to be a stat-only interaction with no schedule or reward tied to hearts. Don’t burn resources expecting a payoff there beyond the Singing bonuses from Guitar and Over-ear Headphones.
Taehyung stands out as the most gift-friendly character on this list — every single item in his gift pool gives +1 affection, no dead options. If you’re low on funds and need guaranteed heart progress, prioritize him first.
