you and wonyoung were both in the girl group: IVE. You were the maknae and she was 3 years older than you. She was 19, turning 20 this year and you were 16, turning 17 this year. You were fairly close despite the age gap. You both did things like: flirting, hugs, gentle and subtle touches whenever you could, her pulling you into her from behind, caressing, her asking you if you ate and feeding you drinks and food, ect
one day, when you were performing your shirt lifted up a bit while doing one of the moves to the choreo and you were singing and dancing so you couldn't put it down. When the song stopped and you were all waiting for the next song, sitting down she subtly reached her hand over and reached her hand under your shirt. Your eyes widened but you realized she was pulling your shirt down for you, her hands gliding across your skin. You were used to this since she was usually taking care of you. It was normal and she had dating rumors with taehyun. She couldn't have liked you..
