Question: do kotoko and irie have a baby?
Answer: Irie has no option but to operate and that's when Kotoko gives birth, with Irie missing it. They have a baby girl and call her Kotomi. Four years later it is clear that Kotoko and Kotomi are rivals for Irie's love. Kotoko, Naoki and their daughter Kotomi go to Naoki's grandparents home.
