A much-posting otaku calling himself Shuutta (twitter @mukaida46) says he's almost ready to believe that his reason for being born was to meet Kakizaki Memi.
Shuutta, who's a 19-year-old university student from Sapporo, buys a lot of CDs and sees a lot of idols at a lot of handshake events, Keyakizaka and otherwise. But he has become a Memi ota (as you can see from his
twitter page), and after the Nagoya handshake event a couple of weeks ago, he appears to have totally fallen for her.
He had several exchanges with her again at this handshake event. Then after the lane was closed for one session, he and another well-known otaku hung around outside Memi's area and she played a bit of hide-and-seek with them, popping out from various places to taunt them.
And on the Sunday, Shuutta was one of those chosen for a special event where members sign things you own. (He had to buy even more CDs for the lottery, I believe.)
She wrote on his cap that she loved him. I think that did it, lol.
I believe this is he, from a TV interview. The caricature portrait of him below is by Memi, done at a previous special event. On it, she wrote: "Handsome (lol)."
