They walked to the class together but they both was silent.

If Zico said something to her, she only nodded to his question.

In the class, Jiyun was very focused to the teacher teaching.

'pssff pssff' Zico trying to called her to ask something but he was ignored by Jiyun.

He do it many times and it makes Jiyun annoyed.

Jiyun turn her head to Zico and push  Zico head to the front while saying, 'Teacher is teaching, please concentrate~'

Zico got a feeling that there is something wrong with Jiyun.

He mutters to himself while looking at Jiyun face., 'What's wrong with her..'

The class end, Jiyun puts her books into the bag.

'Do you have any appointment today? Can we...' Zico words was cut by Jiyun.

'I have a meeting with the Talent Club after this. Please excuse me.' Jiyun went away from there with without saying a farewell to Zico.

'I knew something happening here..' Zico mutters to himself. He decided to follow Jiyun from back  without her knowledge.
