the art style is somehow similar to old xian.. im not quite sure if it's shounen ai but im sure it's comedy. two boys were friends but they have bromance. I remember a specific white haired girl that ships them and a chapter where the other guy gave his handkerchief to the girl so his friend saw it and also ask for a tissue but the other guy didn't give him any so his friend wiped the sauce to the other guy.. pls help me find it.. thanksss

I can't remember so much tbh I remember a chapter where the FL was trying to help a painter then she also disguises herself as another student whenever she would sneak out of school then one time it rained and she met a red head guy who told her "you're indebted to me now" anyways I'm not quite sure if it a reincarnation/ transmigration story... thanks in advance to whomever knows it
