Thank you, translator for picking this series up and completing it at a record piece.
Nice ending for the main couple. After reading Milky Way, Another End, I do wish there 'what-if'? chapters for the rest of the cast but that's wishful thinking.
Overall, I think I like the series. Harem members were a hit or miss. All the teachers and the JK girl are good hits, but the Yankee girl is the biggest flop. Very few scenes or story relevance with her, a forgettable character. Otaku girl may be a late addition, but I like the rivalry aspect of her and the MC trying to win over the teacher. Unfortunately, she didn't have many chapters to dive deeper into the rivalry.
There are some perverted scenarios were completely off-the rails but there were some hot moments as well. At least the off the rail moments can be funny on how they can escalate. MC is O.K, it's a guy who's confused about his grooming relationship with his teacher and wonders how serious the teacher thinks the relationship is.
Overall, it was a decent ecchi series.
