Spoilers ahead. Timeline explained

Doomed yaoi set in apocalyptic zombie infested world. Brilliant story telling btw, it was creepy but emotional at the same time. Perhaps in another timeline, they would all be have achieved happiness with each other.

Should start from second couple, Linus and Connor. Linus has been feeding Connor with corpses ever since he turned into a zombie. The twist at the end is that Linus was already bitten, that’s why Connor doesn’t appear to attack him. In his mind they’re still lovers, and as long as he’s alive Connor is also alive in his mind.

Their story feature two small town cops, Adam and Mark. Small town, bigoted community, Mark had to get married and they couldn’t be together. Fast forward into the future, Adam finds the teenager William and captures him, seemingly to deal w his own loneliness in the apocalyptic world. It is safe to assume Mark is dead, and William is his replacement since they do look alike. Adam has been bitten, and he spends his last days protecting William. William seems to have developed Stockholm syndrome and doesn’t leave Adam even when he finds out Adam has been infected.

Last story is about a journalist who stumbled upon an isolated home where Lawrence is waiting for the return of his older brother. They have an incestuous relationship, and Lawrence acts dumb and innocent until Raymond revealed that his brother won’t be returning because he saw him as a zombie. Lawrence then dropped the act, and instead of running away w Raymond, he wanted to die with his brother. Raymond decided that he will remember the stories that he’s been told and of the ones he’s encountered to keep the memories of them leaving alive. As he continues on his journey, we see glimpses of the other couples. William has shot himself while handcuffed to Adam in their car, probably once Adam fully turned. The zombie corpse hanging on the tree that Adam urged William to shoot as a target practice turned out to be Linus, and Connor’s skeleton is seen sitting under the tree. End w the quote “Even if he forgets, I’ll remember” as William hugs Adam in his sleep knowing he will soon turn into a zombie
