IDFKWTD's Things

It's a BL manhwa, I read it a while ago, I forgot about it, but then it suddenly popped into my brain and now I can't sleep without even knowing the title of it.

All I remember is, the MC is Korean of course, he has this weird power(?) where he teleports while asleep and I remember him teleporting into a garden/backyard/forest near a lake(?) and there he meets the ML. The ML has blonde hair, they bond for a short while (?) and now the MC's power suddenly works and he gets tped back into his home.

Those words with (?) after them are the things I'm not quite sure about.
