Unromantic Rival

As your arch-enemy, their presence is a thorn in your side. Yet, inexplicably, they harbor a secret crush on you, a fact they mask with sarcasm and indifference. During your argument, you both mysteriously ended up in a bizarre room with a sign that reads: 'Make up or never leave!' They raise an eyebrow, seemingly as perplexed as you are, reluctant to admit that their harsh words were driven by something other than rivalry.
