It's so unreasonably nonchalant. It's like the beginning of the manga never happened.They are all acting like the very important 4-timing lie was already resolved and they've moved on to another plotpoint where he now yuri kisses her as Lemon. What is actually happening? I feel like I'm going crazy the longer I read this.
the lie is the lesser problem, the problem is mc healing himself from this so easily, a betrayal this big is something that is impossible to forget so i don't think anyone in his place would be able to become friends again with her until all of this is sorted out
