Who's there? (Na Na Na Na )
If you really want to know just Knock Knock Knock
Who's there? (Na Na Na Na)
If you really want to know just Knock Knock Knock
Who's there? (Na Na Na Na)
If you really want to know just Knock Knock Knock
Who's there?
Who's there?
Who's knocking 我的 Lonely heart
别向邻居 到处打听我的Hobby
当个大丈夫 二话不说带我走
订了餐厅 只会傻坐我家 门口
(等你) 告白有灵感 牛排 已经八分熟Boy
从猫咪聊到线上游戏
(What you waiting drive me crazy
Say you love me be my baby ) Uh hun
内心戏太多话没半句
(Love’ｓso easy show it to me
Don’t be shy boy Knock it Knock it)
爱 放在女孩的心上 是最珍贵 的宝藏
拒绝 测试 我的耐性 就直接 说爱我
Knock Knock 敲敲爱
Knock Knock 喔门没锁 OH
恋爱的礼貌
Knock Knock 敲敲爱
Knock Knock 说声哈萝 OH
Don’t hide and see 当有趣 以为很幽默
爱耍心机 没肩膀 降格变朋友
请乖一点
Knock Knock 敲敲爱Knock Knock
Who's there? (Na Na Na Na)
If you really want to know just Knock Knock Knock
Who's there? (Na Na Na Na)
If you really want to know just Knock Knock Knock
Who's there? (Na Na Na Na)
If you really want to know just Knock Knock Knock
Who's there?
Who's there?
Who's knocking 我的Lonely heart
在我睡前 传张贴图意味不明
熬夜猜不透 是在装忙还是害羞
浪漫节日 暗示有空你还 不懂
(等你) 綵排好一切 刚好 就相约明年 Boy

Who's knocking 我的Lonely heart
用心敲 我的爱 用承诺 保固未来
曾伤过的我明白 浪漫可以平凡
你的呆 让我无奈 告个白 也有障碍
却只想要 那句话 是由你 说出口
Knock Knock 敲敲爱
