Akutagawa and Atsushi had different ways of showing their love, that much was obvious.
Atsushi likes physical touch. He loved to kiss and cuddle with Akutagawa. Akutagawa protests for a few minutes before eventually giving, but he doesnt return the favor.
Akutagawa likes quality time. One time Akutagawa was reading a book while Atsushi on his phone next to him. When Atsushi got up to leave, Akutagawa grabbed Atsushi's black suspenders and pulled him back down.
Both of them liked acts of service. A few weeks ago, Akutagawa was reading a book and Atsushi brought him a bowl of his favourite fruit — blueberries.
And that leads us to the present. The two were getting ready to leave for work, Atsushi going to the ADA while Akutagawa did his makeup for the PM. When Atsushi went to leave, Akutagawa yanked his suspenders and pulled him back (as he always seemed to do), wrapping his black coat around his boyfriends shoulders before harshly — yet not with enough force to hurt him — shoving Atsushi out the door.
