Honestly, I didn't think Kyouko will come clean (almost) about everything to Ren. I loved how it turned out. It is the best that they didn't suddenly change their relationship just because they expressed their mutual feeling. Being able to accomplish the long-cherished dream is definitely more important.
Sensei, arigatou...this chapter couldn't have been better. Loved the ending.
Let's just hope they both can work towards their goal while staying by each other's side (and please no more third party)
