Am I the Ring Grandpa of the Female Protagonist?

Good news: time travel Bad news: Became someone else's ring grandpa Even worse news: it's the ring grandfather of the female protagonist. The female channel is broken, there are palace fights, human pigs, everything. I also want to help the protagonist counterattack... It's difficult, but fortunately, I get a copy of [Exercise Techniques] every once in a while, which is enough to use. As time goes by, I think the female protagonist is becoming more and more like a daughter. There will definitely be a male protagonist for the female protagonist... Sad, sad. When everything settled and the sun set, the heroine abandoned everything and actually said to me: "I like you!" "Meow meow meow?" I was stunned, "I'm just a ring grandpa, meow."
