Ohooo But is there any romance? i don't really want romance in there

First, no. One girl is crushing on him but shes not around much and she is professional for most part so romance is barely there, bromance is more pronounced cus hes around his squad all day.

Second is also no. Dude is really handsome so you might see some blushing around him but he’s much older than most cast members and he shows 0 interest in it, more of family first guy.

Third: Noblesse, no.

Fourth has romance subplot but I assure you that it’s actually cute and well done. You’re gonna love that girl because she’s so much more than love interest. Also the bromance part is both with guy and another girl and he canonically calls them both his soulmates and they are called love trio! So whatever you do or don’t ship them, the love trio is around much more then the crush he has.

Eleceed: there is romance subplot. Similar situation to previous one tho I can’t say romance is done as well cus im not fan of age gaps personally.

Next: not until part I’m on.

Mob psycho has crush but he gets rejected and it’s great moment

Wind breaker has it. And it’s not subplot.

Crimson Reset has none at the moment.

I see! Thank u! ლ(´ڡ`ლ)
