[he squeezes tatsuya's hand]

I want to support you. I want to fight by your side, but more than that, I want to be at your side. I admire your strength, your compassion... I want to help you carry your pain, and I want to see you smile. I want to tell you everything about my life, my thoughts, my feelings... it's so strange to me, to have felt so strongly for someone after only knowing them for a few days--but I do not mind it at all.
