Help me find this bl .-.

I saw this bl manhwa rec and I forgot to save vid and now all I remember is this:

-The mc went on a 2 week vacation or business thing and he comes home to find his brother and his boyfie doing the deed on THEIR bed.

-the bf apologizes and the brother too, BUT the brother is actually a lying ugly faced bitch. The audacity of the brother to pretend to get slapped so the bf would get agry at mc.

I really want to read this so I could see what happens to the brother w/ the annoying face.(〜￣△￣)〜
