Honestly Andou, Oshida and Marie (and by extension BC Freedom) deserve their own proper series focused exclusively on them. They are just a goldmine of comedy and fluff.
Man this was a ride! It was so sweet and wholesome from chapter 1 all the way, makes me think I'm getting diabetes from the constant sugar overdose. Though I kinda think that chapter 5's ending felt rather rushed considering all the built up there was earlier... Well never mind about that! I'll probably start reading the author's other works.
