Bekah's manga / #Supernatural(102)

read somewhere past chapter 20

on chapter 28. The ml was stuck in a realm for over a thousand years, and the mc needs energy sources to survive, so he frees the ml and ends up stuck with him. The ml thinks the mc is his past lover and doesn't leave his side, while getting to learn more about what actually happened in the past and why he's even there. It's somewhat confusing but not bad. Funny at times.
