If you liked Todome no Kiss, you are going to enjoy this one as well. As the title suggests, the drama follows the events of the first one, and it just gives as some information on what happened when the girl kissed the lead and they died in that version of the universe. You do have to watch Todome no kiss to get what it's happening. You do not need to watch Todome no parallel, except from the final episode, that concludes the series. The episodes were shorted, which was nice as it didn't need more, and the performances were good. So, 8 out of 10.
