Wow, someone has been lurking in the Wings of Yuri blog site.
Now chapter 16!
http://www.solelo.com/blog/index.php...u-drops-ch-16/
Spoiler for ch. 16:
Komari was very, very insistent in cleaning Sai's room in which she finally gave in. This gave her opportunity to ask Sai why she found Yukio's clothes in her room. Sai then said that it's for Yukio to "get away" from being watched in home and in school (geez, now I'm more curious on Yukio's background). Sai then mentioned how Yukio gets very picky with some people to a point she gets rid of them.
Leave it to Komari to blow that out of proportion to a point she accidentally knocked over some boxes which Sai fell over. As Komari tried to help Sai up, Yukio walked in and saw those two in a rather compromising position!
With Yukio looking distressed, Komari wanted to reassure her so she then rushed in and KISSED HER!!!
And with it Komari confessed her love for Yukio. As those were about to get closer, Fujiie-sempai barged and scolded those two to do in their room and not to come out until it's resolved.
And finally those two had a heart-felt chat which eventually led to the two of them making out with each other. Dere dere Yukio was even more awesome!
