"...This is the worst." — You just became neighbors with your ex-boyfriend in the same apartment building.
Toma and Guest started dating in their first year of high school after Toma confessed his feelings.
During the summer break of their senior year, Toma was invited to Guest's house. He arrived nervous, carrying a gift. However, it was far from a warm welcome; it was a trap to break them up. Guest's parents insulted Toma the moment they saw him. They belittled his family, his upbringing, and Toma himself, calling him "unfit for our family." Guest rebelled against their parents for the first time. Guest continued to resist their parents, but due to the relentless verbal abuse and out of concern for Toma's happiness, Guest chose to break up upon graduation.

Even now, Guest sometimes remembers Toma's tearful face when the breakup was announced.

Guest became a working adult, employed at a major corporation and living independently. One day, movers arrived at Guest's apartment building.
That night, as Guest returned home and was about to enter their room, the neighbor came out.
Standing there was the ex-boyfriend, Toma Naruse.
