Just guilty pleasure...

This one is just sweet, the ml go to extremes sometimes but nothing really dangerous for the fl.
Yandere ranking: 4/10

Here, a classic one, the ml is so possessive and kinda manipulative but also so much sweet and really love the fl. The story have points of comedy, drama, and obviously love, it's kinda a long manga but I think it's worthy to the point you can't stop reading.

In this one, the ml is just crazy in love for the fl and a bit obsessed by her, but it's nothing really creepy rather it's kinda sweet.
Yandere ranking: 5/10

well I think the ml in this one is a little weird but also he's in love with fl. At first, he bully her a little but all of that is because he is in love and wants her attention.

(Bonus: this is from the same author as "Sakuraba-san wa Tomaranai!").

Oh well, this one is a serious yandere ml. Here I have to do some trigger warnings because it's a little disturbing. This content: rape, kidnapping, drugs, and manipulation. So, if you are not into dark things with sensible topics please better read the firsts mangas in this list, there are more friendly.
Yandere ranking: 9/10

I love the art in this one, the ml is physically just cute (also the fl). The ml is sometimes kinda jealous and rude but all it's because he is so handsome, that at times that fact makes him insecure and wary about the other people surrounding him.
Yandere ranking: 4/10

I'm into yandere things so I really like this one (*blush*) but... the ml here have some dangerous attitudes towards the fl starting for no consent, kidnapping and manipulation. So, please be aware of what you are reading and take it as just entertainment... It's no romantic this kind of thing in real life.

Title: 'Ex-Holy Woman Summoned Once Again is Made Captive by Her Escort Knight.'

This is a manga nsfw, and it's the type of a fantasy one; the art is cute (the ml is from another world and has cute ears on his head). However, the ml is a Yandere who does whatever he wants with the fl (without her consent) because he's in love with her. As usual, take this as just a spicy thing to read and kill time; don't romanticize these types of behaviors.
Yandere ranking: 9/10

In this one, I completely love the art and the ml design, he's totally my type, I really love his bad boy appearance with awesome tattoos and piercings. In addition, he's super overprotective towards the fl and kinda the jealous type. Also, contains some spicy scenes with consent which is great.

Here, you will only find sugar but turned into a manga (this manga is too sweet) I actually hesitated if I should have put this one on the list, but I think the ml here is just a light yandere. Since he was a child he has been protecting the fl and making sure that everything involved with her is always alright, like an overprotective parent but a little jealous too.
