oof quite a rough start but unless his parents are pressuring him to marrying/giving them a grandkid i'd rather have a stable job than a date, i know blind date/setups are common in korea but i would've expected some to just have a marriage that's a 'business arrangement' versus falling in love (tho that's a cliche romcom trope too)
And lol, i feel like a bar /cafe with a sign 'flirting welcome' is asking for trouble unless it's aimed towards like 20 year old ravers and such XP
