im sorry they are a lot (￣∇￣"), also not all of them are fluffy but if my memory is right all of these have wholesome relationships, some may have a rough start but all of them have happy endings. I have the audio of some, tell me if you want them :D
bl or yaoi recommendations on fluffy and just wholesome relationships please
