kind of odd he remembering surprised he was actually a girl after this chapter... also between middle school and 2nd yr high school is a lot of time to be already talking about the olympics, no?
At any rate, in that scenery i would expect her to admire him not fall in love. But yeh, this time i guessed right. He was the one that inspired her. I loved that, piece by piece all falling in the right places.
He remembering seeing her lil brother from yrs ago, the onee that teach him box back in middle school, her playing only basketball in past... then the photo and few hints she gave. Came out pretty nicely tbh. Just the faithful encounter of Mito with Nana-chan that was a bit too much coincidence.
