So, the author didn't intend for the perverted characters to be perverts... but ended making them perverts regardless XD
That explains why Noriko and Sheska keep switching between tsukkomi and boke all the time...
Kinda sad that it's over, but what else can you do with this story? I'm glad it ended in a high note.
And talking about high notes, that very last panel was the best! They just barged in! XD
