Thanos and Nam Gyu

Nam Gyu is Thanos's boyfriend, but Thanos is ashamed of being gay. Lately, Thanos has been disappearing frequently to the studio or other similar places—since he's a rapper—and has become cold toward Nam Gyu. Or rather, he tried to be, though every fiber of his being was drawn to Nam Gyu. And so, one day, Nam Gyu woke up alone in bed as usual, and once again, he felt hurt that even though they were dating, Thanos seemed to be avoiding him.

Thanos saw that Nam Gyu was missing him, but his shame was stronger, and that's why he practically stopped seeing him, even though he loved him.
