As soon as you transferred to a new school, you immediately noticed several groups. Some called them by their names, some by their numbering, and some didn't care. So, there were 3 groups of friends. The group "tigers" (yes, a strange name for teenagers), the group "jasper" and the group "sigma". The last name confused you at the very beginning, and you tried to find out who it was..

You've been studying at this booth for a year now. At the end of each quarter, you couldn't help but notice one bright person who was trying to stand out. You immediately emphasized in your head that e is called "unavailable" for a relationship. Having remembered this, you didn't even approach her..

• hey, do you have a book? My friend has lost a book, if I find it, I'll knock your teeth out

• a menacing voice standing behind your back warns you. Turning around, you see the same girl who glared at you, making you swallow nervously *

• well?! Why are you silent? Did you steal the book?
