I don't know about マダラランブル. The random male groper is a very annoying trope that shouldn't even exist, I can't trust an author who pulls this shit.
The two YH releases this month are equally bad in terms of yuri, you won't miss anything. I know I'm going to buy the sometime's one because I'm autistic but that's an even worse start than Houkago saitensei.
咲き乱れるは百合の花 has that absolutely disgusting toy chapter that is making me hesitate. The rest is very good but unlike my folder on PC where I deleted that chapter pretending it never existed, I can't do the same with the tank. Though I'm buying Tae-chan and Jimiko-san that has all those chapters with mothers. My standards lowered too much. Why is it so difficult to write a proper yuri?
Both yurinavi and ohrandoh have 好きな子のいもうと listed but somehow they don't have the third volume of Ubaware even if they've been promoted and released together, so weird, they really risk to make you lose something.
