I'd pick Manbagi over Komi any day of the week, but this is one of those romantic comedy cliche manga (although to be fair it's not cliche in many other ways if not most) so Komi's going to win of course. I hope she gets somebody nice though. Can't expect something mass-market like this to go the "two girl" route.
Mediocre af guy doing mediocre af things, saying mediocre af words - top tier beauty falls for him because of these... Why don't we live in the world of anime?
Well, on the other hand there are a lot of downsides too, like non-stop cockblocking or unavoidable coincidental encounters with people you trying to avoid at all costs etc.
