Plot wise I found it quite unique but the chemistry and romance felt very flat to me . Comedy wise too its more like a black comedy than a typical comedy. I personally couldn't finish it but a lot of people liked it a lot so you might wanna give it a try, its worth a try atleast
Out of all the kdramas I tried this year Flex x cop, lovely runnner and judge from the hell were the only kdramas I watched without dropping this year Marry my husband and no gain no love started really strong for me but towards the last few eps I lost interest Queen of tears and when the phone rings were absolute let down both started good but went downhill very quickly for me, once they started getting more melodramatic
I have a doubt, so mls roommate has the same name as the other ml (one who has gf) so does that mean the mail was missent to his roommate's email id and not his ? Maybe I missed some detail from ep 1
