I did a AI translation of all the pages, and the basic storyline is the old guy is the high school janitor. He has an ability to use a card to insert a false memory of him saving her life,and he uses that memory to convince her to have sex with him and give him her virginity (flashback scene for page 10-13). Afterwards they continue to have sex.
