lack of COMMUNICATION omg TALK ALREADY

Should change the title tbh

애증(love-hate relationship) 결핍(Lack)

Lack of love could be a translation
But really it is something like Lack of Love and Hate. Or lack of love-hate relationship.

French has is as “Sans Amour et Sans Haine”
Which means “without love and without hate”.

Japanese has it as “ 愛憎不足” which is lack of love and hate.

Seoil does talk about the title on Twitter. It is the love-hate relationship cause by a misunderstanding.
