Honestly, the MC is a real beta. Almost rent-a-gf level kind of beta. He is just some horny dude(why is there always the cliche where they always make it seem like the guy just thinks of sex whenever they're heading to the same room tf).
His reactions are just annoying, it's not even a virgin or experience thing anymore. Worst is how he just assumes she has dated a lot of guys before because how forward she can be, like no bro you're just very beta. Even real virgins have more game.
He isn't having much of a character development and at the end of whatever drama that happens, it just conveniently romantically resolves for him thanks to the girl or the other characters.
Even if there are sweet moments, it's just leaves a bad taste. He can't even tell people off outright and is a total wimp. You're telling me, this girl with the "sad" backstory worked hard to change for this doofus who barely does anything? His biggest effort being, texting her to hang out? I really don't see what redeeming qualities he has over others, and the fact that was a guy with similar backstory to her but he was ofcourse rejected because the mc is such a great guy compared to him.(sarcasm)
Like wow imagine coincidentally getting a girl to like you when y'all were younger when you accidentally held her hand since you're not in the right mind because you were sick in the infirmary which the girl coincidentally, who was afraid of people, was there and decided to touch you then she fell in love because it's the first time she wasn't swiped away for a touch, from then on this girl has always had her eyes on you and even changed herself then even getting popular, that's how she got here and now she's trying to get with you but can't be honest while you on the other hand also can't be honest but act so wimpy that you can't even save her from social situations knowing she's uncomfortable but oh well luckily a character or plot will be conveniently nearby and the problem is resolved, then unfortunately these things keeps repeating once in a while and woah it took a lot for you to ask her to hang out in the holidays, like damn this makes up for all the effort she has done, like woah wasn't it so charming so no wonder she fell for you and, after rinse and repeat where you hardly improve whereas she's the one being proactive, you date, yay! Woah what a sweet guy, you deserve everything that this girl has done for you!(sarcasm)
