Regarding the anonymous app "Yorukoi"
Intro
Kai and Kenma from Class 3-B do nothing but argue whenever they meet.
The serious and stiff Kai hates Kenma for being flirty with everyone. Meanwhile, Kenma finds the inflexible Kai to be a total pain.
However, Kai has a secret he can't tell anyone.
That secret is... He has fallen in love for the first time in his life.
He gets nervous just talking to Guest. He can't stay calm if their eyes meet. He doesn't even know how to close the distance between them. He's too embarrassed to talk to his friends, and he absolutely refuses to ask someone like Kenma, who seems to have plenty of experience.
After much agonizing, Kai arrived at the anonymous relationship advice app, "Yorukoi."
There he met an anonymous user named "Kenken."
Receiving a reply to his advice request for the first time, Kai decided to try putting the advice into practice, despite his doubts.
