Both have time travel involved. In Closer To You, the male lead is transported to the past to save the life of his friend. In Reset Life, the female lead is transported to the past and is able to accomplish great things after having found out what happens in the future. In Closer To You, when he gets transported to the past, there is no "returning to the future". Instead "whoever" gets transported to the past they live their life until the present day. Let's just say this may or may to happen to multiple characters. If you are looking for a simpler version of the Chinese drama Closer To You, I urge you to watch Somehow 18, Korean drama.

both leads end up going to their past selves. in 18 again, the male lead is transported to his past body and lives in the present day. In Reset Life, the female lead is transported to the past and lives in the past life.

Both are great dramas about second chances and having a second shot at life

Both have competent male detectives dealing with female counterparts who are passionate for solving mysteries and crimes. Once they get started, they can't stop following leads. And in both, the male detectives have to "clean up their mess" and make sure to save them from any trouble. Both couples have a Tom and Jerry relationship yet they work so well together. I love both of these dramas so far!

Both a school dramas and the story follows them through college. It's about growing up and first loves. Both the main girls are dorky and are not the prettiest people. Also their crush/first love are like good at everything. Both try to pursue their love and the main lead falls for them. Good light hearted dramas! All can be found on youtube with English subs!
