That is a strange pairing, but I am totally into it now!
Tatebayashi isn't that old, right...?
I'd assume he would be in his mid to late 30's XD
Ha! Now that I went back and really looked at him, he isn't as old as I thought (like, 45) and then I couldn't remember how old Kiri was only that he was in high school and I don't mind age differences, but that's pushing it a little for me.(≧∀≦)
[I would just like to apologize for everything you are about to read under this sentence, there are no excuses, it's not even that late where I am]
So, essentially, what should have happened is Tate-san should have protected Kiri against his stalker (because, that's his job and even though Itsuki shouted 'He's got a knife!', Tate did not have a great reaction time in that scene, how much are they paying that man and is he happy in his job?, so we're gonna fix that right now) and then Kiri, while bringing Jin his midnight snack or whatever, meets Tate-san outside the door and realizes he never thanked the bodyguard. And he does it beautifully, cause he's beautiful, and Tatebayashi is blushing because he's so overcome with the beauty. Tate insists that he was just doing his job and makes an implication that should Kiri marry Jin, he would be under his protection too. Kiri makes some comment like, "I'm in good hands then" or something. THEN, they start to meet every night outside the door and have gradually longer conversations until finally Tate is becoming guilt ridden for developing feelings for someone his master is considering marrying and Kiri is considering 'dropping out' because he has someone else in his heart now.
So basically we got cheated out of a perfectly acceptable side story.
Can we have Kiri x Tatebayashi side story please? ٩(๑❛ᴗ❛๑)۶
