We say, "I love you" to our parents or significant other when we hang up the phone, not because we mean it, but out of habit.

我们会在挂电话时和父母或者某个重要的人说“我爱你”，不是因为我们真的想这么说，而是因为习惯。

youdao

When love is not in, please say blessings to him, after all, once loved.

当爱情不在的时候，请对他说声祝福，毕竟，曾经爱过。

youdao

Love is, thinking about him suddenly when you reading, and then call him, but do not know what to say.

爱，是在深夜看书时突然想起他，想他现在做什么，然后播个电话，又不知道说什么。
