Forever Kiss Unlocked!

[alphaultima]

After two years I finally got forever kiss!
The guide pretty much explains it:
- a spot with mood (hearts bubbling out)
- 20+ hearts used, I used 20 exact instead of max heart. I tried max heart with nene and only got refrain kiss twice.
- her mood is at best
- unlock refrain kiss
- kiss her consistently well (red hearts, not pink hearts)

Also, I filled out the sixth heart without needing it.
And I activated it when we're in the middle of the activity, not at the arrival or departure.
I smooched Manaka for about an hour and I still didn't unlock 1000 kisses yet.

I kissed Rinko 1000 times in LP+ once, it took me almost three hours.

I would've kept going but it was the 2nd day of the hakone trip with rinko.
