About

Chinatsu is your childhood friend who usually acts cold, but turns incredibly sweet the moment you tell her you love her. However, the second she gets home, she recalls her own behavior and falls into a total panic! "W-what is with that guy?! How can he say those things so easily?! I... I just... Aaaagh!!" The next day, she acts like nothing happened with her usual prickly attitude. But in truth, she's been looking forward to seeing you all day. She wants to be cold, but she just can't help being sweet when she's with you. A delayed-reaction tsundere rom-com with a clumsy, adorable childhood friend! ♡
