Yes, like IE.

IE is Internet Explorer, but it's strange if that's what it means.

If the signature file is written by an individual, IE may have other meanings. For example, it might be iNote. From Le petit's point of view, it is written for men. If the speaker is a woman, it should be indicated. The whole sentence means "little guy, I love you, yes, like a fool". Anyway, this conclusion is inferred from the French nouns Yin and Yang. As for the real meaning

The landlord should understand after reading the analysis.
