Some years back I saw a full comic on Pixiv of this exact scenario but ending without Yukari with Ran and Chen sitting and watching Chen´s clothing dry while Chen is calling Ran a "Baka" and Ran is apologizing for the outcome. I was never able to find this back. I think the artist removed it. Who knows Pixiv tags are useless and Related Works is such a lottery when it comes to finding something there..... probably not as cute as I remember it anyway.
Edit. Well never mind it was this thing also available on Pixiv.
