Dude I finally understand why Bitchy eyes hate dowon,the older guy had a crush on taeju too but bitchy eyes had a crush on him for longer and hate the fact his older brother was almost taking away his love from him- it also explain to us why dowon took a sudden liking to Beom- he look so alike to taeju and if dowon really had a crush on taeju in the past which is confirmed to be true that means Dowon's type is black haired and grey eyes man who Should also be a little beefy- bitchy eyes like taeju not only for his looks- since his love lasted ever since he was a toddler which is when taeju wasn't "Attractive" yet
