Fragen über die Beispielsätze mit, und die Definition und Benutzung von "Yuika"

A: "I took Yuika to Asakusa after school yesterday. The oldest temple in Tokyo is there as well as lots of delicious Japanese dessert shops.
We ate strawberry mochis, which is my favourite dessert in the world, matcha ice-cream, matcha rice cake, and hot meat buns. And, we bought a melon-shaped bun for Suzuha.
Asakusa is an absolutely amazing place! Yuika said she wants to take my friend from London here. I hope foreigners will be able to travel to Japan more easily soon."

I changed "sweets" to "desserts" which has a somewhat different meaning. A dessert is a broader term and seemed more appropriate. "Sweets" are like what Americans call "candy" and Australians call "lollies".

I assume you had multiple (plural) strawberry mochis and that you only bought one bun for Suzuha (poor Suzuha).

It was a bit awkward to refer to the friend in London. I said "from London" which can mean they live in London now or are there in Japan now but from London. I'd probably just say "my English friend" or "my British friend", which is less likely to mean they're in Japan now.
