If SweetDrama episodes are locked, first check that you’re signed into the same account used for your purchase and that the payment was completed successfully.
SweetDrama’s current website describes its service as short-form mobile episodes, but it does not currently publish detailed episode-unlocking instructions.
Try closing and reopening the app, signing out and back in, and checking your purchase history to confirm the transaction.
If you paid but the episode remains locked, contact SweetDrama through its official support channel and provide the transaction ID, account details, affected episode, and a screenshot of the lock so they can verify your access.
If support does not reply, you might want to consider posting a complaint on Xolvie in order to bring attention to the issue and try to find a solution.
