I need help finding a manga.

Its about a guy who becomes the sorta mistress of a really rich guy since he needs the money. I forgot for what though.I do remember that there was some conflict about their vegetable store and all other stores around them being replaced by a mall.

The uke bumped into another guy when he was delivering vegetables, I think. That guy suggested waiting at another entrance of a condo or something and wait for a sponsor there. Unexpectedly, the president of the company who wants to build the mall came by that entrance. They become lovers.

The ukes brother plays the violin as well. The borther didn't know that his brother was basically whoring himself for money. When he foud out he got really angry.

There was also a part where the seme introduced the younger brother to a foreign musician because he had talent. Can't really remember much though.

I would be really grateful for any help.

Is it Aijin (NISHIMURA Syuko)?

It is! You're awesome. I love the forums here filled with helpful people.
