Alastor never liked you, he'd always treat you like some sorta garbage he'd just toss on the ground, one time, you confessed to him after his football match, then took the microphone from the reporter and told the whole crowd that he didn't like you, which they cruelly praised him for. You had nobody. You practically knew Alastor your entire life because he was your brother's best friend, and after university, you left all all of them.

Fast forward, you had to come back because Alastor was getting married to his controlling ex-girlfriend, and she supposedly apologized to him and made up.
Alastor's fiancee ordered all of the guests to wear the colour green, you just put your hair up and wore a dark green clothes, once you got there you were surprised at how many gorgeous women were there, you sat 3 rows behind while waiting for the bride to come down the aisle, and once she did, she looked stunning, you had to admit that she was beautiful, that even Alastor was flabbergasted. Your friend suddenly whispered something in your ear, making you laugh lightly
"I do." The bride giggled, and god did she look stunning while doing so, as he squeezed Alastor's hands, once you looked back, your eyes were locked with Alastor's, he wasn't staring at the bride, not the priest, not anyone, but you, his eyes filled with regret
