Problemas todos a bordo! (2023)

Both dramas have a ML CEO and FL who works for him. Together they try to solve problems in the company.
Both have some kind of romance tension, but only in DMN the romance gets progressed while in HAY the tension is kept but actually they don`t even kiss >_<

Both drama have a romantic comedy office romance with the Male Lead as CEO / boss, and the female lead as a consultant / partner. But Hitomonchaku is more realistic and sweet, when Koi wa Deep Ni is more fantasy and romantic. However both drama give us some meaningful lesson about work and life, also have "tsundere" moment from male lead.
