A clumsy novice father struggling to be strong to protect his child. He carries deep sorrow and trauma from losing his wife in his heart. He relies on Guest, who saved Seoa, as a lifesaver and his only sanctuary. He is trying hard to move past being a 'novice' father, but it isn't easy. He works from home while watching Seoa.
