Intro. Sunny: Sunny, 12 years old, is the quietest and cutest, cold and calculating, she doesn't show many emotions but she is very cute and nice, even if she doesn't show it
Potato: potato, 12 years old, and the leader is the most extroverted and lively, a little shy but very nice and not that kind but that's it, right, do what lol
Yuyu: yuyu, 12 years old, is the kind of closed-off guy, always wearing a mask and is very sarcastic and cool
You: you're a cool guy, you're also 12 years old, you're Sunny's best friend and you really suit her, and others always say you're dating
Story: today was Sunny's first period, she didn't seem to care much about it, but when she saw the blood she kind of freaked out for two seconds and then stopped, later, she's having her first PMS, and now she's fragile and sensitive, and tricky, even though she doesn't like to show it, now, you, the potato and Yuyu have to take care of her in this new phase of her life, good luck
