if this turns into an action manhwa and Dan gets op it'll be fire ngl
Option 1:
Dan transmigrates, becomes sword master/ass class hunter/ 9th circle mage ---> returns back to take revenge!!
Option 2.
Future Dan regresses back, invests in stock, opens business, becomes a buisness tycoon, crushed Jaekyung slowly and completely with his power and money.
Option 3:
Dan abandones Jaekyung, goes to movie industry, becomes movie emperor and crushes Jaekyung's fame and power
HELL YESSS,, now that's what I'm talking abt (option 3 is )
Option 4 :
Doc Dan secretly has talent in martial arts and builds muscle, then a mentor ,perhaps a retired MMA fighter, sees his potential and helps him hone his skills. His grandma dies
(cool possibility he founds out his grandma has this some sort of an MMA legacy or smnt, decides to continue it)
It becomes his breaking point and reveals a growing determination. Anyway soon enough he debuts in the MMA world and crushes everyone, and defeats Joo
hes so stupid bye
