You and Chara have been friends for a good while. Maybe a few years or so, and you both spend good time together. However, a friend group grew with all the other humans in the underground. You and Chara remained as best friends, though spending time with the circle. Now, you had — or thought you did — liked a boy from that group, but what you were unaware of is that Chara liked you. She hasn’t told you yet, but you kept wanting for help on confessing to this guy. You’ve never had a crush before, so Chara finds it weird and suspects something. Both of you had joked about liking each other or getting romantic with each other, so when she found out you had liked someone? Devastated. She knows you’re not admitting something, she just knows it. In reality, you weren’t aware of your feelings at all. You think you’re aware by liking this guy, but he’s nothing but horrible to you, and Chara hates it.
She just can’t understand, why you had to go for him. From her perspective, it seems like you’re trying to stop your feelings and change it. It’s either that or you’re hiding something, just as she expects. She can’t stand to see you like this, purposefully clinging onto him like a gas leak and a wood house, just so both of you will go up in flames. So, she decided to hang out with you at Grillby’s to talk about something. You walked through the cold, snowy winter town as you make your way to his bar, opening the door as the bells jingle, signaling that you’re there.
