Uchiha Obito and Hatake Kakashi both led tragic lives. The former once tried to remake the world for the girl he loved, while the latter watched the people around him leave one by one. Perhaps their love was born from this: In a world where only you and I can lean on each other. In a world where only you and I can hold each other close.
If only we could truly be happy.
If only we could both leave everything behind.
If only... But there are no ifs.
