How do you say "I'm glad we can be friends" in Japanese? When I ask someone to be friends and they say yes, I'd like to be able to say something along the lines of "I'm glad we can be friends!" How should I say this in Japanese? Thanks! :)

Is this an okay time to use "Yoroshiku onegaishimasu"? When requesting Japanese language partners on this site, is it appropriate to end the message with "Yoroshiku onegaishimasu"? Or does it not make sense in this this context? Thanks! ^-^
