Summary since people were asking: The girl's classmate (who she likes) came to deliver something while she was taking a shower. Her mom calls her but she didn't hear clearly and came out naked. When he sees her she's afraid that it will make things really awkward and they won't be able to talk normally so she lies on the spot and says she's a nudist and being naked at home is normal for her to make it seem like it's not a big deal.
The classmate is then about to go home but the girl's mom is a total troll and encourages him to stay and since she claimed to be a nudist she has to stay naked to keep up the act. The mom continues to troll (based mom) and tells the classmate how the girl was proud of being able to do a handstand and encourages her to show him. Then a bug comes in and she freaks out 'cause she hates bugs. Finally as the classmate is leaving he tells her that he doesn't want her to be naked in front of other guys because he likes her. Happy ending (no, not that kind).
