BTW, How do you merge a link to a word?

There are times when you will miss what you never had. I wonder how you will find what you so desperately need.

Oh, I didn't figure that one out for ages 😛 Press the button that says
m (manga)
then write the name of the manga
then press the button again.
And it's a good idea to press preview first to make sure the link worked.

Wasn't sure if it would matter....the brother knows, from the beginning that they aren't related

Thanks, book_lover.

You are like the dense main character in a shoujo manga.
