In just one morning, my esper turned into an entirely different person.
Cha Gweonwoo was an S level esper, one of only two in Korea. To Kim Doweon, Cha Gweonwoo was a blunt and cold esper that would call him to guide frequently. To Cha Gweonwoo, Kim Doweon was a guide who he saw as a walking IV.

However, after Cha Gweonwoo was caught in an explosion, suddenly he became all smiles and happy to see Doweon!
