Lemme laugh's Questions (2)

I forgot the name of the bl but the mc is poor college student and he is neighbor with with this rude ml. I Think they were f*** b****** , but ml falls hards for him later. There is an small period of amnesia in between where the ml forgets mc and cannot believe he ever had strong feelings for someone. The manhwa has lots of funny faces and the ml has white hair

I am trying to find the name of a bl manhwa where the mc has a boyfriend who is cheating on him with another hot rich powerful person and the mc falls in love with someone sweet. The mc and the ml are actors i think and the boyfriend also gets together with that person he cheated
