What's the Name of That Book??? discussion

Hello, I hope this gives enough information, I've been looking for this book for a while, and I do remember a few detailed scenes.
I found this book from booktok and I'm pretty sure I read it in the last 3 years, could not be over that.
1. The mmc calls the fmc 'hollywood', because the first time they met, they sort of crashed each others car and the fmc panicked and blamed it on the mmc. Ever since, the mmc thinks she's spoiled which stated the nickname, and their enemies-to-lovers banter.
2. The fmc had just moved into the a new dorm with her new roomates. And apparently her roomates are actually close friends with mmc. The fmc is struggling in math (i think) and her roomates suggest the mmc to help tutor her.
3. The fmc parents are a bit pressuring, with her dad obligating straight A grades and her mom with her high beauty expectations. The mmc parent on the other hand divorced from a young age. His dad left for another women and his mom dying due to alcohol poisoning.
BIG PART!!! --> The mmc has synesthesia, where he can see sounds and remember his past very well. Like he vividly remembers his mother dying and can still smell the alcohol (he hates alcohol). --- He also says that everytime the fmc speaks, he sees blue and yellow lightning.
4. There's this scene, where th mmc was staying at the fmc dorm (since his friends with her rromates), beacuse there was a party going on in his dorm and he doesn't like it. And then the fmc was going on a date with another guy and that guy bought her flowers (red roses if i'm not wrong). But when the fmc wakes up the next morning, the flowers are in the trash and new flowers are in a vase (it was a blue and yellow flower, could be blue iris and moon-something).
5. The fmc also has a weirdly big obsession with mugs and the mmc once gave her a halloween mug (or cowboy) as an apology or gift.
6. The mmc hates having people in his room, but has once let the fmc in a while before they started becoming acquaintances. And that's because her old friend (which is now the head sorority) let another guy drugges her drink at a party so she could kick the fmc out of the sorority.
He also once let her stayed over (during tutoring sessions) and borrowed a (full-body?) mirror just for her.
7. He has a secret youtube account in which he post anonymously of him playing an instrument, which the fmc loves to listen to.
8. There was also a scene where her car breaks down at night and she decideds to call him, and even though he was at a party, he left immedietly to get her.
9. There was also a scene where the fmc was going to give the mmc a treat (rice-krispy), but when she gets to his room, there was another girl wearing his shirt (his relative btw), and he was in the shower. So she decided to bolt and the mmc went chasing in his towel to explain.

Anyways, any suggestions would be much appreciated even if it doesn't fit all the scenes. Thank you!
