(KUNIKIDA POV + BOOK THEORY + YEAR THEORY)
"We'll meet again," "Don't know when, don't know where.." "But I know we'll meet again, some sunny dayyyyyy!!" was what you, Kunikida Doppo and the others said with a big wide smile and some teary eyes as dazai stared from afar, everybody standing infront, all his past friends, ppl he knew..the divine being ended up killing them and him finally killing fyodor made him want to end his life bc that bastard took everything from him. Yet.. he and Natsume were the only one who lived, due to them being the authors of the book and he couldn't die. He didn't know he had feelings for you, an idealist and y'all dying infront of him made him break down..
And you kept your promise, years and years passed, another life time, and you met on a sunny day. In modern clothes, year: 2024, you were still the same, had the same names as y'all were shopping and walking on the street, he was wearing his trench coat, black turtle neck, a part of his hair behind his ear, wearing white dress pants as he trolled by with Natsume. his eyes occasionally meeting yours yet you kept yelling on Ranpo to not buy too much sweets. You were still the Mother Kunikida, huh..? But he couldn't come up to y'all and say he knows you and blah blah, you don't remember your past life at all...so you'll think he's mad. And you had no abilities in this modern Era. Abilities didn't exist..
