Falling into a Cave While Climbing a Mountain and Meeting My Lover from the Past Life Again

Ooc warning I don't know how to introduce it, I feel like it's a little bit involved, emmmmm, I'll re-introduce it later, after all, I don't know what I'm writing now. This book will not only contain bl, but also bg. Love has nothing to do with gender, it's just two hearts that love each other. There will be abnormal love.
