FIRST LOVE movie or series

- Love triangle (equal chance)
- May or may not end up with her / his first love (don't mention)
- Plot-driven, but nothing too serious. A well balance of lightness and drama.
- No annoying female lead ("tsundere")
- REALISTIC, I prefer something that is close to reality, something I can relate somehow. I am a teenager, but nothing that fovused only on school (I am almost 20 anyway). 
- I hate bad acting, like I can feel that its scripted (non-believable)

I've replied to your thread as well, hah. Thanks. I am sad, so I am avoiding watching too sad things. I'd watch #1 first. Thanks!
