IZUKU MIDORIYA:
You get jealous about how close he is with Uraraka, of course, you're good friends with her as well but it's become obvious to everyone that she is crushing on Izuku, him being the only one oblivious to it; Iida and you confirmed the suspicion when you tried to work out who his crush is, which he replied he had no time to crush on people and says you should also focus more on your studies. This then turned surprisingly into a full gossip session where he told you that Uraraka likes Izuku.
KATSUKI BAKUGO:
You get jealous of the amount of time he puts into his studies because you would rather him spend more time with you, not so that he's getting bad grades but so that he pays more attention to you because sometimes it seems to you that the only time he gives you notice is when he insults you.
SHOTO TODOROKI:
You're jealous of how much more powerful his quirk is than yours, especially since he has 2, his quirk is a lot more useful in close range whereas you have to rely more on your combat skills; he helps you feel better about yourself by telling you about how strong your quirk is and comforting you through cuddles.
EIJIRO KIRISHIMA:
You're jealous of how positive he can be, you think he is a lot more mentally strong than you are, of course, he has his moments of sadness where he becomes insecure but you help him through them as he does for you.
DENKI KAMINARI:
You're jealous of how well he gets along with Jiro, it makes it seem that he likes her more than you at times, making you cling a lot more, though he doesn't mind it because he's still confused on how he got someone as smart and amazing like you to call him their boyfriend.
HANTA SERO:
There's nothing you're really jealous about apart from how he sometimes goes off with Kaminari and Mineta to flirt with girls and when getting caught in the act he says they were just joking around and it doesn't mean anything but still makes you get in a bad mood which he fixed that night by giving you all his attention to you.
TENYA IIDA:
You're jealous of how highly he speaks of his brother Tensei while he speaks down on your name; you told him about this and he apologised but he told you that while he loves you that you need to focus more on your studies and fix your attitude.
NEITO MONOMA:
You're jealous of how ahead he is in class, he is one of the smartest while you're more of the average student, with decent grades and an average quirk, which isn't as helpful in battle as his quirk is.
TETSUTETSU TETSUTETSU:
You're jealous of how easily he gets along with people, you're an introvert while he is more extroverted, and when people come out to talk to you two, you normally shy away and hide behind him gripping onto his arm; he normally chuckles at you and tries to get you to introduce yourself but instead, he ends up doing it for you.
DABI:
You're jealous of how trusting Shigaraki is of him, while Shigaraki thinks you're unreliable because of one mess up that you did, and also because you snatched your hand away from his when he went to give you a handshake, even though you knew that his quirk would hurt you.
TOMURA SHIGARAKI:
You're jealous of his skincare routine, and how he gets such amazing soft skin.
ENDEAVOR:
You're jealous of how he is the number one hero, while you're a lot further down the ranking, and also of how many people look up to him after he took his place as number one.
AIZAWA:
You're jealous of his unlimited supply of sleeping bags, it seems that whenever you steal one from him, he always ends up finding it and taking it back while also having a thousand more, it's okay though because sometimes he lets you join him in the sleeping bad where you fall asleep together.
