Look at this face and know, deep in your heart, this is a boy who would love to give gifts for people and nearly cry from joy when they tell him they like it because he's so happy they're happy.

And an older brother figure would be great for him! He would love to hang out with Ryoji and ask him if he can help out or join him on his day somehow. Just tag around like a nervous duck and just enjoy his company, get him little knickknacks he made himself. (Which may or may not work and may or may not explode but it's the thought that counts.)
