I dropped the original series because the main couple is so boring. Yesterday i've seen a scene of kabakura and hanako on tiktok and i immediately watch this OVA. They are more interesting than the main couple. I enjoyed it more than the original series. This OVA makes me want to try completing the original series just so i can watch kabakura and hanako more. The story is well written. They show a flashback on high school life of kabakura and hanako. I wish they would make a spin off of these two. So overall i give it a 7. Thank you to the director formaking these OVAs
