Yeah, his route definitely hits the feels much harder than Sho's or Kei's routes. I was also not prepared to be dropkicked so hard in the feels when I read Jun's route. It does however get better as the days go on, so don't be discouraged!
Kicked me so hard after day 26 and the initial recovery period that I couldn't inflict this anymore to the main character. Jun doesn't deserve me not playing his route, not his fault and I WANT to hug him, but it hurts.
I am however giving him a second chance, now better prepared
