A threesome, as the name suggests, is a trip for three people. If it can be understood in other meanings, anyway, this article is a threesome in various senses.
The heroine, the hero, and the villain have always been a model of "three people walking on the street, all feeling like light bulbs." So what if the heroine is a fujoshi? Haha... The raven once said that behind every "hehe" there are a hundred thousand grass-mud horses running past. This is the truth.
The author doesn't really like the Kurohara (note) heroine, and I'm sorry to those who hate heterosexuals and heroines. Heterosexuality is not a sin. One world can only appear in dreams. It is better for people to be realistic. So please be gentle if you want to spray, it's not me who is wrong, it's the world (DIO: What does it have to do with my stand-in?)
