The Cloudy Brook Academy would open up their doors for a period every month and disciples whose powers got acknowledged would be able to temporarily leave the premises and return home for a couple of days before they came back.
Su Ya's disciple did not leave the Cloudy Brook Academy much only till he was almost into his fourth year that he started to leave on the days the academy opened its doors. In the beginning, Su Ya did not pay it much attention but every time her disciple came back, he acted somewhat abnormally, the smile on his face becoming a little strained when he faced her.
Su Ya had asked him about it before but did not manage to get anything out of him. That person pretended like nothing had happened before but….. Su Ya could feel that her own disciple was intentionally or not, distancing himself from her.
