I'll try one too~~ <<It's hard to find a true friend among so many. Once you find this rare kind of relationship, don't let it go.>> You could probably translate 请不要不在乎 in a lot of ways, depending on how poetic or how literal you want to be. Remember not to ignore it. Don't neglect this love / it. Don't let it go. Don't forget it. ^_^

人海中难得有几个真心的朋友，这份情，请不要不在乎 讓我也來試一試：可以參考一下 It's hard to find a true-friend in the midst of socities. Therefore, please do not ignored this love.

ln your whole life it's hard to find sincere friends in the crowed. .if you possess this relationship.please don't forget to it.
