Letter to Rukia
Rukia,
I would like to formally apologize for my actions yesterday, and assure you that they were not in any way voluntary. I would in fact greatly appreciate it if we would agree to never speak of the events that took place yesterday again.
However, if you have not already done so, I would suggest you let Tamaki know you don't hold his own behavior against him. As someone who has know Tamaki for several years, I can vouch that his behavior was as (or perhaps even more) against his nature than mine or yours was, and I know it will be much simpler for you if you accept his apology.
Sincerely yours,
Kyouya Ootori
