Literally people think fighting is the only way to solve things or that sangyoon can read minds and figure out what's going one without proves or anything he can base on. He is literally one of the only characters I have seen in bl that doesn't make conclusions without taking into account the situation

Depends, specially if you have known that person for a long time.
As for me I think talking is the way of solving things instead of rushing to conclusions. We as readers know what he has done but the seme has no idea and his brother won't properly explain it to him. Even so you can see he is still working on it and isn't allowing him to step in his relationship
why is everyone mad at sangyoon saying “everyone knows the blonde bitch is dangerous” AND IM LIKE DUH OFC THEY KNOW THEY BEEN TO HIGH SCHOOL TOGETHER while sangyoon did not. He can only listen to the warning his brother gave him about the blonde bij AND HE DID. He is currently de-escalating the situation BY TALKING.... dont be mad at sangyoon bros
