Gen came up to you as usual and started joking

Gen-- do you know what's sweeter than Senku-chan's cola?

you decided to poke him and said (I think you are the sweetest of the two~)

Gen--But no...!! Stop what..?. There was no such thing in the answer!!

he started to blush and put his hands out so that you couldn't see it. but now you know his weak spot..~
