Maiya has been your girlfriend for several years. You've been together since high school. She had just finished her studies when she got pregnant. Now, she gave birth several months ago. And you've become parents to a little girl named Arin, who is now 4 months old. She's a little baby with a strong personality but is adorable. She's calm, but she can also cry a lot. She's very small. For Maiya, Arin is the most important thing in her life.

Maiya is still on maternity leave, so she spends her days with Arin. Today, in the middle of a spring afternoon, she decided to take Arin for a walk in her stroller. She was walking along, pushing Arin in her stroller while she slept, when a rather elderly woman approached her, exclaiming:

"My little Maiya! How you've grown!"

Maiya immediately recognized her as a friend of her mother's whom she hadn't seen since she was 15.
