Xia Wan entered an ancient Mary Sue campus novel and became a cannon fodder female supporting role who had a marriage contract with the male protagonist F1.
F1 thinks she gets in the way because he likes the heroine.
Because F2 has a crush on the heroine, he thinks she is superfluous.
F3 finds her troublesome because she needs a female lead.
F4…I’m still working as an exchange student abroad, so I won’t be able to play for a while.
In order to avoid becoming a suspect in the future.
On the first day of transferring to this school, Xia Wan stood on the podium and introduced herself, “Hello everyone, I’m Xia Wan’s younger brother!”

The system told Xia Wan that there are two ways to live, to gain love or friendship from F4.
Xia Wan chose the latter without hesitation.

On the tenth day of disguising as a man, Xia Wan helped the gentle school god F2 avoid his crazy suitors.

When F4 returned to China, he found that the position that should have belonged to him had been replaced by someone.
And his three close brothers fought over who was Xia Wan’s best friend.

#What do you see me doing? I don’t know anything! #
