Sister's All You Need., Vol. 3 (light novel)

A LOVE TRIANGLE'S ALL YOU (DON'T) NEED. Itsuki Hashima, the little-sister-obsessed author whose novels feature nothing but his favorite character trope, presses on through day after frenetic day, despite all his trials and tribulations. Deadlines, love, even his own family weigh heavily upon his mind-but when his friend Haruto Fuwa (still reeling from the awful anime adaptation of his series) discusses a potential love interest, the results could shake up Itsuki's entire social life. Will peace prevail?!
