overall:
this is a sweet mini-series and my only complaint is that i want to see more of the couples.

stepbrother's secret kiss:
this concept is... odd. if we were to ignore that, the boys are very cute and their story is sweet and simple.

secret idol kiss:
a couple bits felt a little unrealistic but i think that's to be expected with the premise. overall very good chemistry. this couple had the best kiss(es) in my opinion.

last kiss:
the title definitely hints at the mood for this episode. i found myself quite sad and unemotional in all honesty. this couple had the best plot in my opinion.
