Hello, dear friends.

I think I’d like to writing about my name. → I think I'd like to write about my name.

Please excuse my poor English.

My name is Yasmine. It’s my handle.

This name was given my friend for me. I like it.→ This name was given to me by my friend.

I got to know each other in SNS to this friend.→ We got to know each other in SNS.

She was a returnee, → She lived in a foreign contry, so she is bilingual in English and Japanese.( It's correct? I don't have any confidence this answer. )

I got her to give me a pronunciation of English Song.

I gave a vocal lesson to her in return.

Since then, she & I are good friends.

She is of a cheerful disposition, fun to be with.

SNS is my weak point but I'm glad to met her. → I'm glad to have met her. (or I glad I met her.)
