UGH I JUST WANT HIM TO HURRY UP AND GET JEALOUS ALREADY

My thoughts too, bro. And it has begun in the latest raw... which I can't read korean, but got the gist.
SPOILER...
There's a character, Alex, coming in that likes our short boy at first sight and wrote his number on the back of his hand with a marker. He couldn't get it off, so it's just a smudge of the numbers and the name and Taewhan sees it. Later he see out short boy with someone and finds out its the guy who wrote the number and immediately butts in. So, interesting things are headed our way.
