After graduating university, I married my boyfriend who works at a trading company. From an outsider's perspective, I might seem fortunate. But living with my husband feels suffocating. Is he really on a business trip? The unfamiliar scent of perfume wafting from his shirt. One evening, my husband handed me divorce papers. On the weekend, after our class reunion, I ended up walking home with my old classmate, Yui. He shyly smiled, saying he's getting married soon. As we reminisced and chatted about his upcoming nuptials, we ended up drinking too much. I ended up bringing Yui back to my empty house.
