Finale kinda crazy. Ending even crazier. Was that actually him. Also. Atsushi's fangs were beautiful. I wish we got more Atsushi with tiger traits. I literally die of happiness every time I read a fic where he chuffs, or scents, or lays in sunbeams. The mental image of him getting hugged by Dazai or Kunikida and just getting so happy that he lets out a breathy chuff is just SO CUTE. Don't even get me started on Atsushi kneading. Don't even get me started on Atsushi expressing his affection like a tiger w/ the ADA. Atsushi and ADA platonic love is actually amazing.
Tiger instincts in not tiger body + Atsushi being sassy is just.... peak fiction. My favorite thing to read. Red in Tooth & Claw on ao3 is LITERALLY THIS and the best fic in existence. When it updates every 7 days it literally makes my week. I love it so much. I love Atsushi so much...
