If anyone is interested in another yuri manga focused on kissing, I would recommend this one. After School by Oshima Towa. https://mangadex.org/title/1b46b76c-bd79-4d42-8b21-e199993fee49/houkago
Did you not see that part in the story where the high school girl kept persistently going after the adult woman with the intent to build a romantic relationship together and how the adult kept trying to turn her down?
There’s a similar manga called “The Tale of the Teapot Hero's Revenge”. It’s about a girl who was wronged by her kingdom and lost everyone she loved, so she uses her new power to seek a brutal revenge on her enemies.
It looks to be a sequel set after Akira leaves and Myuu and Riri take over the tea ceremony club. The two new girls in this chapter first appeared at the end of chapter 7.
