Buyu is a little monster who doesn't know who she is or how long she has lived... Ever since she could remember, she has been carrying a palm-sized light mirror. Only by completing the contents of the bag of tips that appear in the mirror and getting the due reward can she use the mirror to open the time tunnel. Therefore, if you want freedom, any sexy operation is possible! Mint Green Summer: Ex-girlfriend vs. Ex-boyfriend from the band. Social-flavored Sprite: Female anchor vs. E-sports young meat. Crow Heart's first meeting: Transfer student vs. Basketball team captain. Tobacco-flavored jacket: Backpacker vs. Melancholic painter... The heroine has a kidney but not a heart... Occasionally, she refuses the ginseng cock, please let it go~
