What do you love in an otome love interest?

[alias_sqbr]

I don't think we've ever discussed this, and I'm curious!

So: do you have an outright favourite love interest from the games you've played? Are there kinds of love interest you tend to be drawn to? Is it just about the character for you, or does it depend more on the romance arc/how the LI interacts with the specific protagonist etc?

Speaking for myself:

While the nature of the protagonist affects how much I enjoy the story overall, and how well I think the relationships work, I seem to always be drawn to the same types regardless.

I'm always a sucker for dark hair, emotional incoherence, and self hatred. In terms of arc I am a huge fan of the sort of slow burn dumbass mutual pining where by the end they OBVIOUSLY love each other but are both too self doubting to realise and it's RIDICULOUS and AMAZING.

I'm also generally drawn to cold/kuudere characters, tsunderes and science nerds. I generally love any trope more with girls, but am a big fan of younger/subby guys, as long as the protagonist doesn't feel like his mother. (I haven't seen enough non binary love interests to know what I like there!)

I'm terrible at picking specific faves, but some I've really loved:
Saito from Hakuoki: dark haired self hating kuudere
Matthew from Backstage Pass: shy sad pretty boy
Ellen from Magical Diary: girl who applies science nerdery to magic
Victor from Code Realize: Shy self hating scientist

What about you?
