Anyone know the bl?

There was a bl manhwa with a character that looked similar to taeju in low tide in the twilight. But it was a story with a black haired guy who had bad luck all his life, to the point that those close to him died because of this ‘curse’. This curse also killed his parents and a shaman revealed this to curse when he was young.

As a result, he maintained his distance from peers and lived alone, but his neighbour was someone who constantly wanted to get to know him. He put up a front until one day he entertained his antics and talked to him. Just then, the neighbour got hit by a truck and he was reminded of the curse again. But the neighbour didn’t die.

Instead, he seemed to have lost his memories and now had white hair and was seemingly attached to the black haired male lead. His personality also did a complete 180, But, nothing bad happened to him when the MC was in contact with him. If anything, he seemed like a good luck charm.

The white haired guy was hell bent on being together 24/7 for some reason. He has some hidden motives obviously but it hadn’t been revealed then. From what I read, it was alluded that something else has taken over the neighbours body and the black haired MC did have flash backs to a past life that didn’t seem happy. Also the last chapter I read, the MC got attacked by an old man in hospital that was possessed by an evil spirit but the white haired guy managed to save him. Anyone know what it’s called? Oh and this all takes place in a hospital for some reason, they hadn’t left yet
