Korean BL has picked up with such great stories such as Semantic Error, Light On Me, Blueming, Cherry Blossoms After Winter etc.

This story is simple and sweet and deals with office romance between a late bloomer and his new boss.

It also deals with past grievances with a unrequited love and how such trival matters are always not so trival. That everyone has a right to their feelings in situations like these. But it also allows for getting pass those situations through communication.

I would highy recommend this series but people are different and are allowed to like what they like. I read that some think that the main leads had no chemistry. I can respect that opinion but totally disagree.
Chemistry in romance comes in different forms and one of those forms is genuine attraction between people who have a mutual love and respect for one another and a desire to see the other person succeed and prosper and be happy without judgment. In that respect their chemistry is off the charts. Plus to me they also have physical chemistry. But that's just my opinions.
