I have a feeling that he's a regressor that got recently regressed. Maybe at the time or after their bed scene. I've read some spoiler as well that the mc's og timeline/world isn't real. Cuz there was a time that oghuimin wished that both him and ml were just betas. So the mc and ml's current life probably is the product of that wish where they were just ordinary and all.
(⊙…⊙ ) he really came from the future???( ̄∇ ̄") and the other one transmgrated into a novel book or what???!
lets get the story straight already(〜 ̄△ ̄)〜
