Seui was feeling very content at the moment. Although he wondered where this 'bad health' came from, but he knew to never question the blessings that knocked on your door and was very glad to accept that. Even Yew gave him a very envious glance while Cie was curious about what illness he had.

Just that Seui couldn't maintain his happy state for a long time, because Mr.Fou continued "..but considering that this is a compulsory lesson, there was no way to exempt you. However due to your physical conditions, the academy came to an agreement with your family and your family agreed to let you participate in PE as long as there's someone responsible keeping an eye on you. Therefore, from now on you'll be joining the PE with second year class 5. But don't worry, although you'll be with second years , your work intensity won't be the same as theirs" he had an reassuring smile on his face.
