The MC works in a company where a lot of the women fawned over him and often ask him out. Frustrated, he pulls a random guy and declares he's dating him to deter the women
The ML works in IT and is actually attractive but wears non-prescription glasses and has his hair messy and covering his face, only later when the MC declares their fake relationship that he gets a haircut and cleans his appearance together
PLEASE, me and my friend are going crazy becausw we both rmb the plot so vividly but we can't find it ｡ﾟ(ﾟ´Д｀ﾟ)ﾟ｡
