//*Panics* Well... you also did the whole Miko thing, first was the whole "surprise gift" thing with the chest growth for her, which wasn't anything much at first, then you made everyone that stumbled upon her look at them in a way to show it off, then you went another step further by making them even bigger, and your wording also suggests you will go even further for your bias to "improve" your waifu. (Which is also rather sad that you are forcing a change on her and not accepting who she is, you didn't even consult her about it.)
//Then we have the newfound development magic, where once i finally pinpointed how exactly it worked, you immediately went to use it on Miko, and you used an way bigger amount than what we have used on Koa, so basically you put Miko above our own lover.
//Please do not take this offensively, i am merely stating facts.
