Help me find this doujinshi - threesome

It was about a guy moving into an apartment with 2 girls, actually one of the girls invited him, she was the extrovert one, the other girl instead was very shy and even scared of men at first, but she loosened up after a while.
At the end of the story, the extrovert girl gets married to another guy and the other two are now living as a couple.
Sorry can't give you more detail.

Ty for your help!

Yes, that's it! I thought it'd take more time but you were also really fast!
