Oh my goodness thank you so much!! This is it!!! You're awesome!
Looking for a manhwa where the male lead is imprisoned by the seme due to a misunderstanding.
He’s locked alone in a room for a long time and slowly goes insane, spending most of his days staring at a painting of the sea on the wall. The painting is eventually taken away, and shortly after, he kills himself.
After this, the story turns into a reincarnation / regression situation
