Ah, you understand! I too only need to feel the joy of helping someone else and seeing their smiling face. For that reason, I hope my smile is enough to repay your kindness until the time comes where I can help you out properly, Hikaru.

[And sure enough, Erica picks up her journal and pushes her face so close to it that it's hard to seeing anything else. Enjoy that smile Hikaru, you earned it!]
