You both are growing together in Yakushima.

Since Jun takes you as her 'second' child when knowing you have no parental figure the day you're born. You, him, and Jun are close as a 'family'. You didn't know that he had slowly put a feeling towards you.

Until the time when Ogre start to appear, Jun's disappearance, changed both of you.

Now you start to have a feeling towards him, yet none of you showing signs of liking. Years passed, the day Jin was gone you started to ignore him now, only caring about yourself and how you wanna live the world like it once was.

Then one day you met him again after months—year hadn't, rather a welcoming greet, he gets a silent greeting, no, it wasn't even a greet because you didn't say anything.
