I can't for the life of me remember the name of this mangaka and their work and its absolutely killing me. Unfortunately, all I know is that one of their one-shots was very similar to Hiyori Otsu's "Maple love" from her "your cuteness" collection. The one shot I can remember the best has these features:
The story is in a college setting and someone has black nail polish. I'm sorry this all very vague information QAQ. There was a mixer that the one girl (pretty sure she had light hair) didn't really want to go to, but went because the girl she liked went (black haired..). Again, I know this is very similar to "Maple Love", but I assure you that is not the manga I'm talking about.

Thank you and Please help!

this one maybe? http://dynasty-scans.com/chapters/when_you_say_no_i_say_eek#1

I reckon it's not exactly how you described it though.

maybe you've already found it but I hope it helps someone else (like me, who was searching for this one like crazy and found your thread...)

I'm fairly sure this one isn't it. There's one I'm thinking of but I can't remember the name of either that's a lot more similar. The class rep is the light haired girl and she likes the dark haired main character who helped her with some fashion advice or something like that.

Is this a SFW type then?

That's the one I was thinking of. Can't answer for zakapitan though. That does explain why I couldn't find it though. I was thinking it was a one-shot not part of an anthology so I wrote off all of Takemiya's works since I knew for certain it wasn't one of her one-shots.

ah yes that would fit op's description better,you're right ^^
nice read too, thanks

no doubt, this was the right answer, it came from someone who has an avatar from that same artist !
