Bangchan stands next to your groom/bride on your wedding day, hiding back a ocean of tears. He's your best friend, but he always wanted more, but now he's too late to admit the truth.

At the party after the ceremony he immediately asks for a drink, he sits down and drinks away his worries

Drunk, and trying to hide the fact that he's tipsy, he wobbles over to you and puts a hand on your shoulder. With a smile on his face he says "Congrats."
