so it's been awhile since i've read it, but it was basically a collection of oneshots revolving around the same story. all of the girls in each chapter have a love problem, and they all end up on this website that you need a password to. after they enter the website, some guy comes to help them out; whether it be with their make up or clothing. in the process some of the girls fall for the dude, but I remember one of them sticking to her boyfriend.

any ideas?

Sounds like Kaikan Styling.

it is, thank you!
