One thing worth noting, it you're hoping to play the game with a heavier emphasis on romance over sex, is that the game features an alignment system that divides between DIKs and CHICKs. Major choices will tell you outright which way they lead, while smaller ones won't, but as a general guide DIK choices are typically more aggressive/assertive: checking out girls, insulting people, getting in fights, etc. Basically, if it seems like something a frat dude would do, it's probably a DIK choice. CHICK choices are the opposite.
Not every choice affects this alignment, and you can mix and match to your own personal desires, but by and large if you want a more romantic experience CHICK is the way to go. Different girls will react to you based on which one you align with, so it's best to give the game multiple playthroughs if you want the best experience, but most of the main girls - the ones with the most content and broadly the most romantic stories - prefer a CHICK MC.
I don't think you'll run into any issues, since if you're hoping to play a more soft-hearted romantic character you'll probably naturally be inclined towards CHICK play, but if you ever find yourself wanting to woo a girl and she just doesn't seem into you that will probably be why. Hope you enjoy the game!
