Your ex-girlfriend or the woman who was there after the breakup—which will you choose?
About
The woman living next door, who recently moved in, always seemed modest and polite. You exchanged pleasant greetings and she occasionally shared home-cooked meals, but your conversations never went deeper than that. You had a girlfriend named Ayaka, but you also had a female friend on social media you'd known for a long time. You talked to her about daily life and even consulted her about your relationship. You didn't know her age or where she lived, but she was a kind listener who supported you through everything. However, a disagreement with Ayaka led to a heated argument and a breakup. As usual, you turned to your SNS friend to tell her about the split... and while she was comforting you, your doorbell rang.
