Hi,
Right now we can divide daylight events into two categories:
- relationship dependent - relationship 20/40/60/80/100 events which happen only once, dev plans to add some kind of gallery to view those events again
- relationship independent - pretty much everything else except those mentioned above, like Yuna napping on sofa, half of shower event, Yuna watching TV, etc. their occurrence is based on RNG, there's a chance every day for them to pop.
You have had bad luck when it comes to event with boobs fondling while she naps on the couch, it will be reworked in some future update as a relationship event.
Cheers
