Feels like the author tried to cram too much in, and important things got left out as a result. Would have been better if it were more focused on Ran's coming out to herself and left the Forced drama out of it.
Cute, I think. But it's probably just me, but at times, the two characters are drawn rather similarly, they kind of look alike and it's hard to see who's who.
Also there's no need to be irritated by Risa, she was supposed to be a confused little girl.
She wasn't all that confused. To me at least, sure she 'broke down' at the end, but I see that as more like something that was gonna be taken away from her and she started blaming Yuuka for stuff. Her inner monologue wasn't indicative of some deeper thought before Yuuka wanted to break it off, so I have a hard time of seeing her as confused. She wanted a substitute and got it in the form of Yuuka.
I did like the time-skip part though, it shows that she spoke the truth at least. Don't get me wrong, I like this one-shot, but Risa irks me with how she put the blame on Yuuka for not dressing 'girly'.
^ All of this. Also.. i think Yuuko is pretty cute even with short hair :)
