(It's not a crime) It's just what we do——演唱者：竇靖童
主題歌電影版MV中，竇靖童與“
安生”、“
七月”跨時(shí)空相遇。飄渺靈動(dòng)的曲風(fēng)中，黑白畫(huà)面與彩色電影片段交叉剪輯，竇靖童清澈磁性的嗓音和“安生”、“七月”的羈絆成長(zhǎng)交融，歌詞娓娓道出女生心事，詮釋剪不斷、道不清的大膽青春。在這支MV的片尾還剪入了一段竇靖童對(duì)電影《
七月與安生》的觀后剖白。
歌詞：
Some time ago， some time had gone。
One came back crying， one cold dawn。
I told a lie， she made a truth。
It‘s not a crime it’s just what we do。
All the times you‘d think that I was holding back。
Did you think I was just running from what I can‘t have。
Yesterday you called and you were crying。
I think the saddest words were I‘ll stop trying。
Said the world deprived you of your wisdom。
Then you asked me do I like who I‘ve become。
Every Time you‘d make me question all the things in me。
Did you think that all I wanted was to believe。
Was to believe。
