During a barbecue with Jun-Ho, Ha-Rin, and Soo-Ah, Ha-Rin secretly rubbed Jun-Ho's crotch with her socked foot, causing him to react. Soo-Ah noticed his strange expression and said she was going to the restroom. Once she was gone, Jun-Ho scolded Ha-Rin, but she immediately pulled out his cock and started giving him a blowjob. He worried that Soo-Ah would hear them even with the door closed. When Soo-Ah returned, Ha-Rin quickly moved to block her view, pretending she needed to use the restroom herself to give Jun-Ho time to zip up his pants. Jun-Ho realized it was a close call and that he needed to have a serious word with Ha-Rin.
Later, while Jun-Ho was talking with Soo-Ah, she suddenly kissed him. Ha-Rin saw them kissing, and Soo-Ah immediately ran away from the scene.
While cleaning a building, Jun-Ho saw Ha-Rin spill coffee on a doorbell camera. He accidentally rang the bell, and she opened the door, pulling him inside and kissing him. She said she couldn't stop thinking about him and had been holding back, realizing she had deliberately thrown coffee on the doorbell camera to get his attention. He initially rejected her, calling her desperate and saying he was only there to clean, but felt guilty when she got upset and agreed to help her.
He confirmed, "I just need to fuck you?" and she spread herself for him. After a short time, he questioned why she was so desperate when she could have any guy, and she said she wanted him specifically because "the way you do it makes me feel good." Happy with this, he gave her what she wanted, kissing her as he creampie her. Back in the moment, he wondered if she was after something, attributing her enjoyment to his skill as a "sex genius." She began performing oral sex on him again, making him hard, and led him to the bedroom where he repeatedly hit her sensitive spot. He asked why she held back if she was enjoying it, then made her orgasm and creampie her a second time.
He asked why she waited for him instead of hooking up with someone else. She explained that she had terrible taste in men who only wanted to "fuck a hole, not a real girlfriend." She said, "You are different. You are relentlessly trying to find my sweet spot, and when I was close, you went in." He replied, "When doing both, it feels good."
