Kazama is the best wing man. Shutting down comments and deflecting others from interrupting their Kouhai&Senpai time.
We all could use a wing man such as he. Him, or Sakurai. I'd prefer having Sakurai.
The last 2 panels in my mind:
"..." [ Kazama's Inner monologue: "Isn't that fine!! Since we'll be having a daughter which will look just like you. ( ͡° ͜ʖ ͡°)" ]
"Isn't that fine!! Anyway, let's go eat some udon! ( ͡° ͜ʖ ͡°)"
well, one party is definitely much more mature than the other party.... not that i hate this cute couple, but definitely the relationship wouldn't going everywhere as longe the kouhai is not growing up, her mentality at very least...
