Please help me :>

Hello. Can someone help me find the title of this story? It's a story about a small high school girl who has a crush on a well-known or handsome student. Both of them like each other secretly or more like their feelings are mutual BUT both of them think that it is a one sided love. It has a simlar art style of Old Xian (19 days). I've been looking for its title for two days already. If you know the sauce please kindly drop it (⌒▽⌒) I'm really craving for some sweet and fluffy story. ε=ε=(ノ≧∇≦)ノ
