Confessing to an older girl who's clearly not having it

Someone is shooting their shot at an older girl (언니/noona), and she is NOT interested. She hits back with 'Grow up, kid. You're too late.' The sender refuses to give up: 'Why won't you give me a chance, even just once?'

She shuts it down cold: 'Dating younger people isn't my type.' The sender spirals: 'Damn, my only crime is being born too late… I'm just gonna disappear.' Suddenly she softens: '...you're cute. I love you, don't disappear.'

The sender immediately calls her out: 'Then say that 'I love you' like you MEAN it.' She goes: 'I love you.' And the sender, fully aware it's just pity affection, types back: '... same.' The reluctant "fine I guess I like you" energy is immaculate.
