Iz this good? Does this have a romance or love interest???

It's one of my favorites of the genre. The author made the game concept truly something of their own, the characteristic art style is unique, MC is the genius funny egocentric type opening up to friendships along the way. A good share of comedy, a lot of angst (second season) and a lot of thrill. No romance, strong female character are actually strong and badass :D
There isn't a lot of people here because it's free on webtoons

So, does this have romance or annoying, blushing for every little thing female character??

It's finee, there's no cringe annoying romance. It has subtle romance so far, she's probably gonna be the FL, but it's only rarely shown, probably also gonna be like that in the future chs. Then again the FL is actually likeable, she's capable and has her own character & goals, their relationship is natural from friend to close friend.
DAMN I CAN'T WAIT FOR THE NEXT SEASON
