Why are people acting like they've never kissed before ... https://dynasty-scans.com/chapters/tadokoro_san_web_comic_ch19#4

I actually did forget about that, but didn't they also kiss on their date?

Didnt they also kiss when they had the bath/sleepover with awesome mom's help? Or was this mis-reading / wishfull thinking on my part?

Also in the photo-booth during their date

Might be forgetting more but can't remember.
