Guy forgets he's dating someone mid-argument and she has to remind him

A chaotic KakaoTalk conversation where someone is dramatically venting about their 'hyung' (older guy they like): 'Does hyung hate me? Or is he just using me? I like him so much I can't even cut contact even though I hate it...'

The blue-bubble person (the hyung himself, apparently) loses patience and hits back: 'I KNOW you like me. BECAUSE you like me, I'm dating you and responding to your texts right now, you idiot... Seriously shut up before I break up with you.'

The sender is stunned: 'Huh??? What??? WE'RE DATING???'

Hyung: 'Yeah we're dating. Wanna break up?'

Sender, immediately: 'No sorry goodnight I love you'

She was so deep in her spiral she literally forgot she was already dating the guy she was crying about. Peak anxiety brain.
