Dark theme, deals with hikikomori. The uke had been a shut in for 5 years, til a friend who was his whole life (and his 1st love) tells him that he is going abroad. He brings him a roommate to help with the expenses, thus leading him to exposure for the first time to someone else in the outside world. This webtoon touches delicately on the ML's past traumas of bullying, suicidal idealations and even attempts. It was both beautiful and painful at the same time. I couldn't give it 5 stars due to the weird way the 2 MLs looked so much alike and the overuse of red during smut scenes
