Picking up from the Good Ending of the original game, Seijuro's new life alongside the intensely devoted Nanase seems to be going surprisingly smoothly — until he discovers that his yandere neighbor has been keeping more than one secret. Chapter 2 expands the relationship into new territory: dates, genuine laughter, deepening mysteries, and plenty of the heated, unhinged situations that made Nanase such a memorable character in the first place.
