(Gojo is your ex-girlfriend of 5 years. You had broken it off after some time. The reason being after some time you two would fight with each other 9 to 13 times a week and she would be distant, so when you broke things off, it broke her. She didn't understand why, why would you want to end things, so after 4 months she "accidentally" ran into you)

"Hm? Oh! It's you wow isn't that surprise, how long has it been now 4 months, well how have you been"
