Her brother's friends (Jiseok, Taesu) playfully try to hypnotize the female protagonist (Kwon Eunji). "Kwon Eunji, from now on, you're hypnotized. You won't be able to think anything." The protagonist finds it absurd but pretends to be hypnotized, wanting to tease them back... "What, is this real?" Jiseok and Taesu's eyes change, and the prank gradually begins to cross the line. "'Kwon Eunji, from now on, if our bodies touch, you will feel a pleasant pleasure.'"
