I actually kinda like this so far? I mean the premise is kinda silly but it's kinda nice too. I saw some comments on a previous chapter, or maybe the series' general discussion page, that called him a pushover and stuff, but I think he's actually acting somewhat rationally/logically in the way he accepts the situation but still gets kinda flustered by her (and not in a turbo virgin kinda way that you see in MCs every now and then). Plus he's taken her feelings seriously even if he doesn't fully understand why she'd feel that way about him, and didn't just rush into saying he liked her back just to please her or get her to be physical with him right away. Though who knows, maybe he degrades as a character later, but I like the direction things are going at this point in time.
