Fumi wo Tsuzuru

Sasamura is curious about Ayano Otsuka, a mid-semester transfer student with beautiful handwriting. Otsuka comes to the Sasamuras' stationery store and tells him that she wants to send a letter, something that's unusual these days. Sasamura wants to get closer to her, but Otsuka has a secret that she can't tell anyone.
