Itsuki falls asleep at the kotatsu and has a dream. He dreams about his darker middle school days. His mother had just died and he falls in love with a certain girl, but... Back in modern time, Itsuki celebrates his book becoming an anime and has a mixer at his apartment. Haruto brings over a board game about being a light novel artist and they all play. What kind of results will they all get in the end?
I'm really sorry. I can only 
see you as my little brother.
Entschuldige, für mich wirst du nie was
anderes als mein kleiner Bruder sein.
Lo siento mucho. Solo te veo
como a mi hermano pequeño.
Lo siento mucho. Solo te veo
como a mi hermano pequeño.
Désolée, je ne te vois
que comme un petit frère.
Mi dispiace, ma riesco a vederti
solo come un fratello minore.
Me desculpe. É que te vejo
como um irmão mais novo.
Прости, но для меня
ты только младший брат.
