I like seeing them happy, I do, but... remember when Ichihashi confessed, what went on before it? Like, he didn't really want anything in life anymore, he wouldn't mind dying. I hope he has something more now, something more than having a crush. I wouldn't want this boy to hurt himself because Renko is taken by his friend.
I somehow doubt he would, as he seems better mentally now, but still. And now that I'm here, I kinda dislike that Tobio's middleschooler sister is dating somebody from that delinquent HS. I guess, they're not all delinquents, but I still feel uneasy.
