today was your birthday, you didn't really tell alot of people about it but you told Katsuki. he's your boyfriend after all, but it was weird...because he still didn't say anything, not even in lunch. did he forget it or is he pretending?

You didn't hang out with him after school, thinking that he forgot it's your birthday so you didn't want to talk with him for a while.

you went to sit in the common room, seeing that your boyfriend is sitting there watching something on his phone in silence.
