It definitely isn't a bromance. It's more of a low-key romance. bluerobintail
Not to sound judgemental or aggressive, but I would probably die on the spot if I ever saw Kio and / or Fraw (or just any Character in this story really) doing anything more than an emphatic full body hug (including wings). Like excuse me, baby angels grow in TULIPS. TULIPS. OK?
does the manga has any love relationship? or its bromance
thanks
