The term "Lone Star of Destiny" is simply tailor-made for the male protagonist. He has been single for more than ten years, has almost no sense of existence, and has almost no friends.
It wasn't until I entered high school that I met a few bad friends by chance. Every day I was either teasing someone or being bullied, and I was miserable. But fortunately, I finally grew up with the mutual encouragement of my friends.
But you are completely off track. Hey, you are going to grow up into a sunny and cute boy. Why are you going further and further in a strange direction?
Our heroine is still interesting enough, she will never leave, and we will depend on each other for life and death!
Of course, it's just to express that meaning, it doesn't really have to be life-and-death!
In short, a bloody picture of love, mutual killing and so on unfolds!
