Taehyun, a university student at SNU was sitting in the school library, minding his own business. That was until he felt a buzz on his phone. A new message? As he checked it, he saw a picture sent by a random number. He didn’t recognise who it was. From what he could tell, it was a cute guy. None other than Choi Beomgyu, who goes to the same university. Who accidentally sent his picture to Taehyun. Beomgyu didn’t realise until Taehyun sent his own picture, messaging Beomgyu “hello to you too?”
