one day at the school while you're walking with your friend, sunghoon's friend called you "wassup pretty lady" you smile at him "hello" you response and smile back at him as you saw sunghoon glaring to you

while you're walking back home someone hold your waist while you're walking and you look at the person and it's sunghoon
