Both are Japanese LGBTQ+ films about a seriously dysfunctional relationship. The ML is reluctant to be in a relationship but ends up eventually giving in to the persistence of his love interest. The themes of both films are similar in terms of dysfunction, acting style, cinematography, closted homosexuality, and infidelity.

- Same Female lead
- male lead posing as a girl
- good romance
- one is historical while other is modern but similar vibes between the lead

Both have main leads who have a bit of tension when they first meet, but their chemistry and banter pull you in right from the start. They also both have very sweet, feel-good romances that will leave your heart warm and full!

So as similar as Mistress it's about husband is disappearing and cheating while wife is a strong lady and loyal.

Fake sibling/family relationship
FL gets jealous sometimes
Smart ML

Both modern C-dramas feature a mature, mutually supportive and heartwarming relationship between the leads. They face potential misunderstandings and relationship challenges by trusting one another, rather than with tropey fights and breakups. The genres are somewhat different (Love o2o has more light silliness interspersed with the romance while Forever is more sedate and focused) but both will have you smiling throughout.

topic: babies raised by others. In this drama the ML receives her 5 years old daughter. He didn't know about her existence. The mother left her to be raised by him. He's a famous actor and he doesn't care about his daughter. He pays a caretaker to raise her and they fall in love.

I add this drama because of the topic of babies raised by others that maybe family or not. In My Lucky Star, the FL was raised by his uncle because her parents died.
His ex-boyfriend betrayed her: he got married and his wife gave birth to a baby girl. The wife died and the ex-boyfriend became a widower. The baby needed a heart transplant and he committed a crime to get money. He went to jail and the FL decides to raises her as her daughter.

Both have humans who turn into monsters.
The world facing a huge human crisis.

You Yi and Yan Wei dynamic just reminds me of Dao and Koi though two dramas set in different times. These are the same since Dao is also a writer and Koi also protects Dao.

Childhood friendship, misunderstanding, meet again years later and love prevails! Love is Sweet is way better though

Both
- lost their mother early
- kids had to fend for themselves (although Go Ahead adults were much nicer & heartwarming)
- had the elder brother figure that took care of the younger siblings
