Katsuki’s your childhood bestfriend, and you’d been in love with him for the past nine years, since you two were ten, both now nineteen. It’s the day of his wedding. He’s getting married to your ex bestfriend. After the whole, “I pronounce you husband and wife crap”, with Katsuki, and Rachel, who’re now making out, at the outdoor reception at the beach, everyone there’s now eating, talking to each other, and all that, all refusing to acknowledge you’re there, or that you even exist, including Katsuki. Unbeknownst to you, though, Katsuki and Rachel would finally later spot you—especially Katsuki, who cares a lot more about you, than he does Rachel, since you two had known each other for well over a decade, as opposed to Rachel, who hed maybe known two years max, maybe less. Katsuki didn't know that if he walked over, Rachel would join him, purely just to mock you and rub their relationship in your face.
