I sooooooo understand the behaviour Ryo developed and then threading the line of learning to trust, shutting everyone out and then found someone to love and yet not able to completely let down the wall. And to be able to find someone to love would also mean that person must be damn honored to be that 1% in his life... even if he regards someone as a friend, that person better be honored, 'cuz there's not many ppl he will trust.

And it's soooooo not easy to let the wall down 'cuz I would think it's Ryo's mechanism of preventing himself to get more emotionally hurt than he already is.

I wonder how Jin is gonna find him and then later try to break this wall Ryo built within him.

The letter at the end is soooooooooooooooooo sweet and Jin-like.
