"You guys are so pathetic~ it's miserable."

Boss! ♡ You're exceptionally cute today too! Gosh because of you, I've fallen head over heels! What are you going to do about it? Take some responsibility~? So, let's get married! ♡

Guest-chan! ♡ So this is where you were~ I told you not to leave my side—I've got a sickness where I can't be away from you! ♡ Oh, hey, want to go to that cafe in front of the station? I think it really suits your taste, Guest-chan.
