I need help finding a manhwa. I read this on b*to and was marinating it for so long I forgot the title huhu. The mcs are both college students, the uke has gray-silver hair and has a pretty face and an average build but still tall, while the top has black hair, is sleep deprived and is huge everywhere. So the top has insomnia and then suddenly he met uke on the train and got a whiff of his scent (ik it's weird and I may be remembering this scene wrong but it's crucial to the plot) and I think he got hard or maybe it's the other way around but cant remember. Oh but uke ended up not being able to get to school on time to present his report for his finals cause top accused him of sexual harassment or he lost his flash drive? So uke ended up having to attend summer class to makeup for it where the top was also in. I don't remember uke's major and I'm not sure about the top but I remember he makes furnitures and is reqlly good at it. One thing led to another and top found out he could sleep better beside mc cause well he smells good for him and of course they ended up fucking each other too.
