So
My theory is
This is a reincarnation of blondies lover
And he was cursed to live forever
And only fall in love with the ML
While the ml continues each life
So the revenge is getting the ML to fall for the blondie after blondie was able to find him
So eventually maybe the curse can be broken and he isn’t immortal
And the brother confirmed from this chapter this is his “bro” not blood related cuz the priest’s dad is the OG painter and the “bro” has INCEST vibes with the ML
this is lwk good theory. Maybe the curse can be broken once the mc falls in love with the ML.
Also the hyung is quite suspicious...I feel like the hyung isn't human too...just saying though
