So the guy is the head of an app company which the main girl is contracted to work for.

The main girl is a ‘love expert’ who is contracted to work for a romance app game the company is making.

The main girl then sees that the guy is unable to court his love interest, proceeds to provide love counseling.

The guy then managed to get together with his love interest, only for the main girl to find out that she is now in love with the main guy.

The main guy later got his position in the company hijacked by his subordinate, only to learn that he wants the main girl to console him instead

Cue they learn that they like each other, happy end
