I just read this BL webtoon (not sure if shounen ai or yaoi) a few months ago but i forgot the title and the entire plot: i can only remember this one scene where the seme and uke fell asleep in the living room while hugging. The uke woke up first in the morning and saw the seme’s sister/friend looking at them while grinning and taking pictures of them, while the uke was just frozen in the seme’s arms all embarrassed
