I read the sequel before this one so I didn't expect it to be so good. I mean better than the sequel.
Their personality and relationship is pretty unique and refreshing. Sometimes you just forget that they have an age difference. It's interesting how the seme (Shima) has a mature air while being younger than the uke (Ryuu). Ryuu showed a lot of growth (personality wise) throughout the manga and that's what makes him so special. They really are adorable.
