Even after Professor Ikeda recommends that Ibarada proceed on a doctoral course, she can't make up her mind about what she wants to do.

As she does, Kosuke looks on in fascination.
Meanwhile, Himuro has caught a cold due to the changing of the seasons. Worried for her, Yukimura goes to her apartment to check on her, but the flush and heat of her fever has given her a coquettish appearance that sends Yukimura's heart racing.

In outer space, they say that ethyl

Обнаруженный даже в космосе,
этилформиат обладает сладким запахом...
