Well based on what I understand on the raw the seme want to do the uke but it seems that the uke is still reluctant to do it . So the seme finds another uke to do which he did in the past too. Also after reading the translated and raw chapter you can notice that the seme is so sex addict even though he stated that he like the uke . I'm tired of that kind of manga that "I like this person but I'm still gonna have sex to other people so he might get jealous and fall for me immediately or do I really like this person maybe I'm just horny so lets get sex to anyone I find first"
Well some of you may find this boring ,innocent or whatever but we have different opinions anyway dont mind this too much

I don't think he actually did it with the old neighbor (present) but only in the past. Old neighbor seems to have some domestic Abuse experience with his boyfriend (past) and then the markings on the wrist (present).
So I feel like the end of vol 1 was the misunderstanding trope and not that he was cheating on him even if the 2 main aren't official official yet.
Pretty sure he's not sleeping around with the neighbor or anybody, plus he seem to be serious with our uke as seen through ch 1

╮( ̄▽ ̄)╭ nonono, I totally get it. I'm ABSOLUTELY 100% on the same page as you, I took it off my want to read list. It's so cliche at this point that it makes me feel like why even bother. And I can tolerate manga that make sense, where I can see from their perspective., even the crazies. But stuff like what this seme does is way!!!! off from relatable. That "off your rocker" style of manipulation is not cute or charming to read in the least
Uggh I wish i didnt read read the raw the seme is so asshole altought I find him cool at first but sigh
