Am always lonely's Manga

I dont usually comment but my god i seriously cant take the turn this is taking. It started off very cute, felt very personal when it came to insecurities and struggles but then it just went miscommunication after miscommunication. Honestly im sad but i cant stand it. This part is a spoiler!!! Maybe its too early to say but i am not liking at all the way the second male leads feelings are changing just like that. Glad the guy is getting over the girl but it feels very shallow to just have him change his feelings just like that
