This is a reality show but the dynamics between the couples and characters are almost the same. They both remind you of young first love and the fumbles we made when transitioning from teenagehood to adulthood. Plus this show is filmed like a drama

- Sport romances
- Both MLs are athletes
- Both FLs support the ML athlete - translator and club manager
- Both have sport athleisure companies who look for athletes to sponsor their brands
- Both have typical bullies in a team who try to bully ML
- Parents push the male leads in a sport they didn't want to play

Both are warm and cozy romantic melodramas. Both have seasons in the title and they actually occur during those seasons. I also suggest watching them in the season they are set in. The female lead in OSN and male lead in SS are librarians. Both male leads are low key and total green flags.

Both male leads fell harder for the female lead

Strong female leads who approach romantic relationships casually

Both female leads are lawyers

Both female leads are the stronger one in the relationship

i don't know if this is helpful but there's an amnesia subplot in both that was dragged out endlessly and then everything wrapped up in a rush

Part 2 in particular is similar because it takes place after one of the characters died and was resurrected and is still misunderstood by the world as being a ruthless but powerful killer who practices sorcery (Wei Wuxian and Naksu). Their partners (Lan Zhan and Jang Uk) are now powered up characters who fear no-one and are able to protect their loved one, regardless of their past or what the world thinks

Both have immortal male lead characters who suffer from their fate until the female lead frees them. One thing I found similar was that both male lead characters had guilt and pain and constantly had to bury people throughout the time they were alive

The ML's sister is in a "sham" marriage, the annoying SML who can't let go of the FL, FL trying to leave one complicated relationship to get into another that's equally complicated, cute and affable ML pursuing the FL first, even the aesthetic on the poster looks the same
