It was an "I like you but never thought of you as a possible romantic partner but a very special person" so she can't accept her love... or at least not right away. Then, what SJ did in the bridge was the right call... She needed to start this development BUT what she does next is not, because she needed to make her intentions clear but then pursuing her and pressing for an answer and then be surprised when she declines? no no no no. Qiu Tong needs her time alone because everything is rushed and confussing for her, no wonder she tries to run away her head and heart must be about to explode.
And woaah yuzichan, really? find another girl who happens to be lesbian and also fall in love with her? that's not how it works either, Sun wasn't interested in love and wasn't sure about her preferences until recently, until she met Qiu Tong! She shouldn't give up on her so easy... yeah they need time but find someone else meanwhile? uggh no thanks

Black as night, black as coal
I wanna see the sun blotted out from the sky
