Ohhh you were talking about his reactions towards the colleague of Koneko.
I did see one blush scene i couldn't explain with the reason of him being shy because hes talking about koneko and blushing because hes saying things that takes a lot of gut.
When he leans over to close the door on her side, it could be 2 different kind of reasons,
1. hes feeling the doki doki of being close to a woman. After all hes a teen and don't most teen boys react to almost anything? xD
2. hes feeling embarrassed and thinking something along the line of damn i've become cool?
But yea even i think that scene is looking a bit dangerous.. Let's see what happens in 2 chapters when Koneko walks in on them doing w/e they were doing in the preview. (〜 ̄△ ̄)〜
I agree with not liking the ML btw since it really shows in his age just how childish he can be.
But the other things you said:
It looks like the page with the number 55 matches the same page from chapter 24 that is uploaded right now. So I don’t think the numbers are accurate.
And to what you said about touching some girl’s boobs- I looked at the preview and isn’t that just the FL? It doesn’t look like anyone else but the FL who grabbed his hand and put his hand on her boobs. I think you might be mistaken on what you saw
if you look at ch 57 preview hes with the chick and FL gets mad. and ch.36 preview seems like he touched some girl's tits. but right now, hes basically cheating by meeting up with her behind his GF's back and blushing. i dont think he full on cheats (like sex or kissing or holding hands) but he still pisses me off
