I got a friend that are like this. Bro always asked me for advices and i always meet them together and i'm just like "bro, just go out already". I don't hate him whatsoever, but man she clearly loves you, quit asking me for some advices 💀
Haru tries and either fails or succeeds in bring Toshi and Yuki together and later befriends a girl whose interests align with Haru since she's annoyed by Toshi and Yuki's antics and they worked together to bring them closer which either fails or succeeds. While trying to bring the 2 childhood friends together, Haru and the girl fall for each other.
