Decoders other users are not compatible with your data, because each user’s unique encryption key
The virus reportedly wants victims to write to the e-mails happychoose@cock.li or happychoose2@cock.li and it threatens the vicitms that their data will positively be lost forever if they tamper with the files, which may be true, since some ransomware viruses use CBC (cipher block chain) mechanisms that break all files if you tamper with one of them.
It also appears that the virus is part of the Globe Imposter ransomware family, some of whose variants can be decrypted, but this is another variant, since the ransom note is a bit different in color, so it is not yet known whether or not the files can be decrypted. Once Happychoose ransomware enters your computer, it may begging scanning for and encrypting documents, images, presentations, audio files and all sorts of files that likely have the folowing file extensions:

After the Happychoose ransomware has already encrypted your files, it ads the .happychoose extension to them and they start to look like the following:
Paying the ransom to the crooks is something that we would advise against doing, because researchers might be able to come up with a solution on how to get your files decoded for free later on. For instance, Emsisoft have created a GlobeImposter Decryption tool that works for most variants. But they are yet to update the tool to decrypt this variant, because it may be new and undecodable.
Either way, our best advise is to take a look at the “Remove” part below, backup your files and remove this virus and then try to decrypt COPIES of your encrypted files with this tool.
