Go Back Couple has the same male lead. Also, it's another more mature romance. Deals with similar mishaps due to miscommunication between the leads.

Son Ho Jun does a great job in the supporting role for The Light in Your Eyes. If you really liked him in Go Back Couple, you might want to watch it as well. TLIYE also deals with time changes and familial relationships.

Love with flaws also has a cute LGTBQ+ couple. It also deals with homosexuality with less of a conservative taboo response. One of the brothers is gay and runs a gay bar and no one really blinks an eye. He doesn't give a sh*t what anyone else thinks.

- Well cast, great acting

Differences:
- The plots are completely different
