Yes, i agree. This manhwa indeed have psychology aspect. Even the other manhwa from the same author also have pshycology tag. The moment when i read this for the second time, i notice the author give us a sprinkle hint about psychology (Eerie staring, weird smile, abnormal diet) with the comedic undertone. And yeah, i kinda tired from the comments that criticize and hating both the MCs. But some of those comments are also fun to read.

Something the author didn't want to show us at the moment. The way he suddenly stopped after explaining himself while looking at sunbae, the "hmm?" Then when he reached for sunbae's hand while his expression looked worried... it intrigues me (⊙…⊙ )
