Both are Psychological dramas that make you think about your life and the meaning of everyday life, joy, conversation, love, friendship and the beauty of simple joys and conversations.

Both healing/psychological lowkey indie kdramas.
Both base its beauty on introspective dialogues about life.

One Day Off instantly reminded me of Be Melodramatic.

Both are Republican Era dramas in which the FL's family is destroyed by either the ML or his family.

When I saw the preview of Circle of Love, I automatically thought of Provoke. They are in the same time period and are both short series with hot male leads.

Both involve two worlds and lots of ass-kicking martial arts.
Both have an element of mystery. Things are not as they appear
Both need a season 2 both I doubt we will get it lol

If you liked books from George Orwell, Not me and The Eclipse is just for you.
While The Eclipse is more like 1984, one man against the system and looking for system that wouldn't be manipulated.
Not me has themes from Animal farm. People are gathering to go against ministry. People above them with power but someone else wants to take the power the people would gain and use it in a bad way as well as those pigs.

If you look for action drama after Not me. This is just right for you. It's making me sad it's pretty underrated because I really loved the story and the main couple. The common themes you could look for is standing up against the system, going after power, cool fight scenes, romance, close death scenes, tension between two leads.

The similarities is the work place, the relationship at work, funny friends but also dark past. I can't really compare it that much since Bed Friend is R-rated but a lot of things were actually similar there. The top best friend Jack/Jade. Terrible step dad and ignoring mother. Trauma. Homophobic people. Well, what is common between Uea and Cher is that they have undying love for their siblings. Cher and Thoop are not related by blood but treat each other like siblings too. Uea was able to go back to his hell for his loving sister that was the only green from his family. Cher was taking care of Thoop as well and even appeared in dangerous situations for him. In Bed friend it's Uea who's sexually assaulted, in ABAB it's Tian, Cher's past crush but her and Uea went through similar hell. Both were sexually assaulted by their step fathers. I'm not sure if Uea was also raped but I wouldn't be surprised. The difference is Uea didn't kill himself even after living in this hell for several year but still fought with PTSD. Tian ended up pregnant and couldn't live with herself anymore.
King and Gun actually shares more things. Both when they find the right one, they love him undyingly. Both were financially supporting their boyfriends and protected them in front of danger. How King beat Uea's ex and Gun hit Thoop's step dad. Both are visually outstanding and their boyfriends have them wrapped around their finger. They both come from problematic families who didn't accept their relationship at first but allowed it in the end. Both are pretty rich but fall in love with the poor guy with golden heart. And Cher and Uea are both sassy to their boyfriends and casually insult them ?. Also both Cher and Uea decided to leave their boyfriends at the end. Cher because he felt he's not competended to date Gun and because of his mother. Uea because he couldn't work at the place where boss molests him and needed time alone from King. The difference is King was the one who just couldn't leave Uea alone and didn't stop looking after him until he found him. Gun respected Cher's wish and distanced himself but Cher couldn't live without him and waited till he graduates. Both stories have amazing happy endings and both kept me entertained to the end but for rewatching I'd choose Bed Friend because I just enjoyed this story more. It was even more matured and my type of genre. But I loved the comedy in ABAB more.
