The story starts with the MC about to blow up the student council office because he is bullied by the student council president and he hopes this will put a damper on their Christmas party that will be held at the office tomorrow. His childhood friend, who he used to like, suddenly appears saying that she heard some rustling and thought someone might be jumping from the roof so she came to check.
He tells her that because the student council president, her boyfriend, bullies him (shows her a minor bruise), and he can't take it anymore so he is going to take revenge by blowing up the office. While spiraling, he has an epiphany that since she is the girlfriend, she must pay for her boyfriend's sin and show him her nipples, to which she promptly does. One thing led to another and eventually they have sex, with the mc constantly trying to compare to her boyfriend.
After finishing, he tearfully asks what she sees in the bully president, to which she start listing them with him retorting: his muscles (which he uses to hurt the MC), him treating her to meals (using the money he takes from the MC), and his kind nature (of none was shown to the MC). The final reason, however, was that the bully president was the one that saved her from her dad's violence (a huge scar on her head). She scolds the MC, saying that if he was a little bit interested in other people he would have noticed it (the only thing he knows about her is her blood type) and that the bully president noticed immediately. When the MC asks her why she had sex with him, she said she saw little value in herself so if doing that could prevent him from blowing up the office then that would be a good outcome.
Realizing the error of his ways, the MC decides to remove the bomb (not for the bully president though, but for her) and she also says she'll talk to the bully president to stop the bullying. While she is waiting outside for him, she gets a call from a very distraught MC saying that he's going to kill himself, realizing they had nothing in common. He starts talking about the time when they were little and had a Christmas present exchange, he gave her a handkerchief as a present. He then asks her why the handkerchief is under a table leg, to which she replies "Because it's just the right thickness...?" And he blows the room up (presumably with himself in it).

Overall, I like the art, the girl is very cute, and the sex scene was decent. The story stopped itself from being depressing (kinda) by having a dark comedic ending. I'm interested in the next work the artist will be coming out with. Supposedly it will be with a tall emotionless girl who has a cat and likes Forest Gump and Shaolin Soccer and an otaku who is shorter, clean and smells good, has a dog, and likes Shawshank Redemption and The Green Mile.
