It's ok bro, I feel the same too. It's the first time I've loved a harem girl this much and I am so fucking scared. I don't know what I could do for her if she could not win or achive her deserved happiness. Sometimes I stayed up all night worried. It was so bad, I had work to do too. I've been trying a lot to prepare myself for the endgame so I would not break down if she lose.
Sorry about the rant anon. We should keep believing in our Yotsuba.
