Imagine what if Tsukishima Kei just broke down one day. Although he may not show it. He feels rather empty. Well, probably emptier than he usually have. Unlike the usual walking empty vessel without something to fill him in, he felt like this very vessel cracked so much that nothing can ever fill him in. And that's how breaking down felt for him. No tears flowed. Just the emptiness of his soul stared and reflected from a shattered mirror, reminding him that he wouldn't be normal no matter how much he wanted to. No matter how much he tried to see through his soul.
