this is probably ooc but i need copium rn /lh /j
Anyways Min-Su showing Thanos Robot Dreams because not only does he like it but he also needs a good cry. Thanos really likes it as well but after the ending, he's sobbing, full on ugly cry sobbing, holding onto Min-Su and begging him to never leave or replace him. (and also takes as him passive agressively suggesting that he wants to break up with him). Min-Su points out that it was neither of their faults that they grew apart and, while Thanos understands, it just makes him sob harder because there may be an unforseen factor that splits them apart.
Min-Su is suprised to see Thanos so emotional, usually he's cracking jokes and while he does get depressed, it's always...quiet, a sort of numbness or empitness rather than large emotional outbursts. Not that he minds or judges him for it, it's just rare to see is all. Min-Su holds him tighter with his arms and legs, as tight as he possibly can, the closest their bodies and hearts can get to one another and says, choking up a bit himself, that nothing that he can do would make him leave him. Thanos smiles at that, still sobbing, but it's nice to hear.
Eventually, they both pass out on the couch, emotionally exhausted. But...despite that, Min-Su is glad he showed him the movie. Because he got to show him just how much he loved him.
