I read it a few years back and remembered that I enjoyed the fluff/love plot but can't remember for the life of me what it was called. It's about a model who is trying to find his idol who has suddenly disappeared. He finds out that the ex-top model is now a manga artist and begs him to help him become a better model. So he ends up making a deal where he'll be his idol's model for his work to try and convince him. Any ideas?
