放學回家后，你就趕忙拿起手機，加了朱志鑫好友

“你好，我是蠟筆小鑫”

“你好，我是柒七”

“明天放學學校圖書館好像有個活動，你要去當志愿者嗎”

“好啊好啊，大概幾點啊”

“五點半左右吧”

“那五點半圖書館門口見！”

“好啊”

“顏柒，你在干嘛？”你哥左航喊道，“你吃不吃飯了，手機是你的飯是不？把手機給我，我倒是要看看你在玩什么”

“左航！你信不信我呼叫媽媽，我在做事，等會再吃”

···············································吵了很久·············the second day·······························

五點半，圖書館門口，一位白衣少年站在那里，“顏柒！我在這里！”，少年的嗓音低沉而又有磁性。

“好的好的，我來了?。?！”

···········································

“這個有點沉，來幫你拿吧”

“哇哇哇謝謝謝謝謝，如果你是我哥該多好啊”

“你哥是不是叫左航？”

“哦莫，你怎么知道的”

“他是我同桌，聽他說他有個妹妹，叫顏柒，長得很可愛”

（ 你內心os:左航！你妹的愛情就靠你了！）
