HAPPY Jdramas with no breakup or separation

Can someone recommend Jdramas which are  happy  romantic. (HAPPY ENDING)

1. Happy or romantic dramas

2. No breakup or separation 

3. No over acting (I don’t want anime’s acting)(eg. Nodame Cantabile) 

4. amazing kisses and chemistry or sexual tension with lots of flirting 

Examples:

In-House Marriage Honey

Happy Marriage!?

koi-wa-tsuzuku-yo-doko-made-mo( love last forever)

nechan-no-koibito(our sister’s soulmate) not exactly comedy but nice feel good drama.

please HELP!!! Thank you
