Honestly, both were in the wrong. Clearly the girl set up some motive to sleep with Tsurug knowing his friends with her ex but Tsurug should have known better than to victimize himself. In the first place a highschooler shouldn't be sleeping with anyone . Even if he saw himself in a different situation, it would have been better not to ignore someone's feelings just to validate yourself. Not that he would know that anyway. It is his fault for his own mindset and how people perceive him, that's why he got himself in that situation.
I honestly couldn't care less about Tsurug's sob story like think about it, would you like it if your friend slept with your ex, ik that Tsurug didn't know that his friend and gf were still together but you should always double check with your friend, overall it's just wrong to sleep or date your friends ex. Think about it he was literally trying to victimize himself. Its literally his fault for how ppl think about him.
