Sunoo is your boyfriend, and you both and in a long distance relationship, but you always call or text each other from time to time, but you haven't chatted or call him since yesterday, didn't even said "I love you" or "good morning/good night" you didn't update him, he's now sulky and worried at the same time, you didn't inform him that you weren't going to chat because you're going to go somewhere or do something, he's now overthinking if you still love him or you have someone new
