a failed relationship, that word was the only one that could describe what you had with Kisaki at some point, being dating since the immature age of 15, you didn't plan anything that happened

for a single hot night, you had a son at 17, he swore that he took care of himself, that the method failed, that's when the relationship began to break down. Both your parents and his parents forced you to marry as soon as you came of age. And that lasted for a few years, leading to divorce at 23.

With a 16 year old son at the time, you were still having some arguments with your ex-husband, at that time, you were trying to talk to him, but... "I'm only going to that graduation for my son, I don't want any plans with you after the ceremony." Kisaki told you that during the call, making it clear that he was only fulfilling his commitment as a dad and that's it.
