Mori Ogai and Dazai Osamu

Mori calls 15 year old Dazai to his place.

— They told me that you argued with Chuya again.

• Not true.

• Is it true?

— We didn't argue.

— Then what happened?

— Scientific discussion.

— Why was half of the training hall destroyed after it?

— Science requires sacrifice.

Mori just slowly covers his face with his hand, realizing how unbearable Dazai was, but deep down he loved him very much and was worried about Dazai.
