help

They went on a mission together where hajeong found out that most espers even some of his old friends who he thought had died were actually being experimented on and even brought back from the dead. The ml already had a hunch that the mc had soul swapped and by the end of s1 he became sure of it cuz of hajeong having a fever and releasing his og guiding frequency
Hope that helps (⌒▽⌒)

THANJ YOU!!!
