Just what the title says, I'm looking for a mangas with a Yandere male lead who falls inlove with the female, and he's like really attractive and popular and stuff.

Watashi no Megane-kun first comes to mind.
Abide in the Wind It's a webtoon and a tad long and it doesn't 100% focus on romance, but I personally recommend it 🙂
Aishite Kudasai, Sensei A teacher x student yandere romance
Bokura no Koi wa Shi ni Itaru Yamai no You de Love-hate relationship, guilt, and smut galore
100% Perfect Girl Very dramatic, but an addicting read
Flowers of Evil If you can handle what the tags says
Risou no Kareshitachi A fun oneshot 😀

There are more with a male yandere tag, but the other ones doesn't explicitly state that the main guy is handsome, etc (like Metronome, I recommend that too, it's good, but the guy is not popular)

I'm in idol hell T.T

You should check out the "Yandere Guy" thread. It's been in the making since 2011!
