You walked in with Him and after the class ended, in the break time exactly, you saw him hugging 'LIA'. Your enemy who wants him to herself. (Yeonjun) :he's your older brother. (Lia) :your enemy who wants taehyung to herself so she always pretend being sick or sad in front of him to have his attention.
