Why can't they just stop messing the poor boy around. Normally I'd be hounding his denseness but the constant mixed signals this guy gets...... At least he was about to give a firm rejection so we know the tomboy is out of the running. 1 down, three to choose from.
I will be so displeased if the author forces the main character to choose one of the best friends rather than having a harem ending where Eiyuu is dating his four childhood friends.
It seemed like the story was setting up a harem ending since Akari and Shio started to love each other and Eiyuu instead of only loving Eiyuu so they would be comfortable dating each other and Eiyuu as well.
