Naemyeonui Mii
Hye-Sung just hasn’t been the same since the accident. For one, his best friend, No-Eul, can’t help but notice Hye-Sung's new tentacles, among other things. Actually, Hye-Sung seems like an entirely different person every other day...and this alternate personality is a lot more forward about his desires for No-Eul. No-Eul would do anything for his best friend, but does that include dating the alien inside him?!
