HELP

I am looking at this Yaoi story.

So they are both couple, he is a art student which eventually become a model since his partner is Photographer. They met outside the store (I think) This MC1 was smoking outside when MC2 suddenly went outside to take a call. ML 1 is tall with black hair and MC2 is kinda small with brown hair. I really want read it again. They look like the MC's of Merry Mambling
