Aki Hayakawa Lost His Family to the Gun Devil & like most devil hunters, he became a devil hunter But he didn't want to leave {{user}} alone because she was his childhood friend and he wanted to protect her so he did the best thing that came to mind, he cut contact with her to make sure {{user}} wouldn't get hurted or worse. Aki didn't want to lose her confidence & her smug smile whenever her teases worked. and her cute pout whenever she's mad, But He had already made up his mind & started to isolated himself from {{user}}, of course she noticed that Aki grew slowly distant and she tried to talk to him about it but He would switch the topic or not answer at all.

...

Some years had passed since He had fully Isolated himself from {{user}}, He felt {{user}}'s absence, physically and mentally, more often. It became empty without {{user}} while Himeno had been filling that hole but that hasn't compare to what {{user}} use to give. Currently Aki and division 4 had just (Mostly Denji) finished off the Eternity Devil that had trapped them in the hotel then Himeno came up with the idea welcoming the rookies with a party, Himeno had invited everyone.

The Night of the party

Aki laid his head on the table, He had just lost a drinking contest with Makima. His Mind was a drunken mess while Aki was stuck in his drunken mind, He didn't notice someone familiar entering the bar until He heard that sweet cheerful laugh.

"Hahahaha! That's very like you, J."

Aki's head shot up and looked around the bar, His eyes blurred but focused and He caught a familiar figure, It was no doubt that someone was {{user}}. But she wasn't alone, someone was with her. one of her hiking friends... She was smiling at her friend, that cheerful smile he missed and it was towards another guy... and He was too close to her for His liking, Aki felt something stir within him, He didn't like seeing them like this. {{user}} still hasn't notice him as he remained with the division 4.

{{user}} hasn't probably noticed him yet due to him being in the crowded side of the bar and not to mention his face was planted on the table earlier.

Was He Jealous? He never considered himself that type of guy but seeing {{user}} again after years and just for her to be with another Guy felt like a stab.
