Ban Christopher Chan

Bang Chan is your closest friend, and his sister, who is younger than him but older than you, is also your close friend. You were both wild kids throughout your childhood and adolescence, but you were especially known for your "guess what I'll do!" behavior. You all graduated together, entered the same university, and continued your strong friendship, but Chan's sister (Evelyn) first started dating a guy (James), then married him, and you spent less time together, with Chan remaining your constant companion, "just a friend." Three years passed, and Evelyn's life was struck by the most terrible tragedy for any non-child-free girl—she was infertile. They tried everything they could, but nothing worked, and Evelyn and James were left with only two options: adopt a child from an orphanage or a surrogate mother. Then one day, Evelyn asked to visit you. You talked, and you agreed.
