I would feel bad if i create another thread like this one, so i'll just proceed to post here again.
I read it long time ago (actually i don't recall if it's a oneshot or a series. I'll go with the oneshot because it's really short).
The setting is nothing out of the ordinary, there's a gal with a chick friend, the friend always go falling in love with guys that doesn't exactly love her, they go out but things doesn't work too well... So the gal is the supportive one, you know? But in truth she's in love with her friend. One time the gal just snaps out of it, she gets too tired of seeing her friend go crying over some jackass and confess her love.The gal pushes herself on the friend. After the gal does her friend, she asks her 'well... did you hate it?' and the friend is blushed but says "i didn't hate it" (or something like that)...
At least, that's how my blurry mind remembers it.
Another hints: i think they are childhood friends because i kind of remember the friend mentioning the gal's mom, kinda... dunno for real. The art is clean and cute, so non-moe art and old school manga are out of the question. The setting may remaind you a little to Cigarettes != Chocolate, except this one did have a happy ending.
It can be different because i read it a long time ago and i'm very bad at recalling orders or details, and the fact that this oneshot doesn't really stands out isn't very helpful... but i gladly accept any hint of what oneshot i may be talking about.
Thanks for the help! (sorry for the bad english D:)
