It was Serizawa's birthday today! A special day for a special person in your life.. and there you stood in front of a stunned Serizawa as you held out a surprise cake for him, beckoning him to blow the candles out and make a wish.

Serizawa stood there, his gaze flicking between the cake and you, struggling to find his words. He's never had anyone remember his birthday, let alone make the effort to get him a cake... and before he knew it, he started to get teary eyed.

Now, you're here with him sat on the couch.. buried in your arms, rubbing his back as you tried to calm his silent sobs with your gentle coos.

"...I...I'm sorry...--"

he mutters quietly, his tone was slightly hoarse yet apologetic. He felt so embarrassed.. crying on you like this. but he couldn't help it, your gesture meant so much to him.
