The uke is not that short but still seme is taller (to the point the differences are visible).
As for the plot, I feel like it can be developed so much but it ends with many plot holes. However this one is not a heavy one (despite the fact that uke is the uncle-in-law of the seme)!! VERY VERY VERY NICE ART! And hot bed scenes. lols.
