I need more QAQ

Maybe 'Bad friend', 'even if you don't love me', 'solo for two', 'love me doctor', 'the third ending', 'driver's high', 'rainbow city (is super slow burn :))'

Thankyouuuu

You're welcome!! Tho my recommendations are yaoi, not your typical shounen-ai. But try them, maybe you like them.

Bruh that's like every rapey webtoons ever, the seme dude is violent asshole but love his bottom so much.

No, that’s not really what I’m looking for. I mean more like gap moe, where for whatever reason my expectations of the ML’s personality are subverted. Initially they might appear outwardly cold, angry, calculating, tsundere, etc., but in reality they’re a dope for their partner. Rape or violence toward them definitely isn’t part of it….

Another example I thought of is “I Declare Vengeance.” In this one the ML is a badass rich gang boss, but it turned out he’s been innocently crushing hard on the MC for years and is unexpectedly super sweet at heart.

Lol, don't worry I know what you mean. Btw you mentioned tsundere, but what you described is literally just tsundere, cold but actually warm. And what I mean is, tropes like this are super common. A lot of ancient yaoi is exactly like that. Since you need more recommendations, just look at the cover where the seme looks like a jerk (Or ML like u youngsters called it now)

Saw your list is full of webtoons, read Japanese BL manga bruuuuh, the OGs, you're missing out a lot of those devoted tsundere semes
