@Suzushiiro Hmmm. You may be right with that pairing. But, tbf, she is the side of the tank that takes on the full assault. Could very well just be doing her norm and talking to any guys that try to approach her crew.
As for pickup-pai, I don't think he tries to hide his scum at all. When it comes to relationships with woman, he is total scum. But he seems nice otherwise. Like, some totally messed up guy threw a bike at him and he organized a rescue mission for it asap.
I thought for a while that he might be a best bro, but terrible lover sort of chara, though the last meeting made me question it. Still not sure where he was going with that. Perhaps he considers the lover of someone he is interested in as an enemy, or perhaps he was just trying to figure out their relationship. Or... perhaps when he saw their relationship, he started questioning if the bike incident was a coincidence and was trying to carefully tread into the topic.
Or perhaps I am putting too much thought into this. Either way, he is an interesting character. Hope we get a side story from his gf's point of view one day. Really curious what the hell is going on with him and why she stays with him despite everything.
Also, when she approached yamada in the library, I kind of thought she was intending to accept her as a 3rd member of their relationship instead of asking her to forgive him or buzz off. If that was the case, the possibility that she is bi could also be explored
Gosh I like this series too much. End of rant
