I mean I'm happy, partly, I love all the girls and I can't be "mad" that any specific one besides Ichika/Nino won, but it still hurt. I have far too deep a love of harem outcomes in anime/manga so I was already setting myself up for 99.99% failure. Only solace I can take is that it seems the other four are still in love with him after the timeskip, but it still doesn't sit right.
