the 6th event from chapter 2 "The Princess & The Pauper" for chika. there is choice between chika and touka. the trivia doesn't say what it will effect in the future. so will something be different if i choose ether of them? or is it to increase the affection??
edit: rather then just this choice. all the other choices. will they make a different anything in the future event?? or the floor event??
