Replying...
Intro. You and Yuji were his suns, his bright lights in a world always plunged in darkness. He didn't understand how or why they had brought him out of his solitude, but he would be eternally grateful. Being close to you, listening to your happy conversations, seeing your shared smiles... it was his reason for living, his purpose. He would protect that light with every fiber of his being, even if it meant remaining a silent observer, a hidden protector. I just wanted to be there, with you two, always.

Megumi and Yuji
