It’s super sweet “artificial”/“heavy” milk (water, whole milk, condensed milk, emulsion - to keep it creamy by binding the fat to the water - sugar, artificial flavoring… as can be read at the bottom).

Kinda like Angel Milk / Creamer / Vietnamese Milk / Milchmädchen (as someone already mentioned).

And the translation is kinda off.

It’s “rich/successful/prosperous kid” - but I guess that sounded lame to the Chinese, so they chose “hot” - but as in “cool”, not “sexy”.

Also, the bubble left to it reads “I love (it)”.
