"Aww look Kacchan! It's our graduation photos." Izuku said enthusiastically. They were looking through an old photo album, reliving old memories.
"That shit was so long ago. I still can't believe they let Pinky graduate." Katsuki slowly walked over to where Izuku was sitting on the couch.
"Yeah but no one even knew she and Kiri were expecting except Aizawa sensei and Recovery Girl." If he remembered right anyway. A new thought occurred to him watching his partner. "Remember when I was your cane?" The old greenette with now graying hair snickered.
"Yeah yeah" Katsuki sat down next to his husband with a loud grunt, and set his cane aside.
Izuku flipped through a couple more pages until he came to one with balloons and streamers, it was their debut as the Wonder Duo. They were all geared up in their Pro Hero costumes ready to go on patrol.
"That was fun times huh Kacchan?"
Katsuki coughed a little but smiled. Soon after that they had opened their own agency. He flipped to the next page, his smile growing. "Damn Nerd proposing before I could get the fucking chance to."
Izuku beamed and kissed his husband's cheek. "You were just too slow Kacchan." The next few pages were of their wedding. He teared up at the part where they said 'I do' and kissed. "That was the second most happiest day of my life." He sniffled.
"Second?" Katsuki scuffed before getting snuggles from Izuku.
"The first was when I saw you were alive after the war." Izuku said softly.
Katsuki blushed and coughed again. They spent time reminiscing on their wedding and the party after. Izuku could still talk for hours without Katsuki saying a word. The blonde, turned gray, was used to it and smiled, loving how happy his husband looked.
Izuku went on. "Oh the kids!" The pair had never had biological kids of their own but 'adopted' several over the years. Mahoro and Katsuma visited frequently to this day. Eri and Kota graduated UA and were now pro heros but also visited when they could.
Izuku looked over at his husband who had been more quiet than usual. "'m fine. Just tired Izuku." Katsuki smiled softly, reassuring Izuku. His red eyes were half closed, his head resting on the other's shoulder. Izuku kissed the top of his head before flipping through more pictures.
They had retired three times! Izuku chuckled at the memory. After the first time they had gone on a vacation and came back bored as shit. The time after that they were asked to come back for a secret mission. They were both happily retired now for many years.
Izuku yawned, closing the album before speaking. "How about we head to bed, Kacchan?" He smiled but soon it faded when his husband didn't respond. "Kacchan?" He poked his partner, checking for a pulse and breathing.
"Kaa-!..." He panicked for a moment, realization hitting him. He kissed the still man leaning against him and nuzzled his face in his hair one last time. "I love you Kacchan." He told him, tears began to fall from his emerald eyes.
Izuku sat for the longest time, holding his dearest person close to him, sobbing. Until he finally had the strength to call the police.
Katsuki had lived a good, long life with the person he loved the most. He died in his arms with a smile on his face.
