I was reading this manga since I was a high school student and (then) I shiped Sensei x Chun-Chun so much. The last chapter came out when I was like 19 and I was furious that she didn't pick sensei who was her first love. Now, re-reading it at 23, I realize how real-life ending this is. We don't always end up with our first love, and this manga shows you exactly this! I truly feel happy she ended up with Mamura but my heart clenches so much for Shishio. Well, all in all I found the ending bitter-sweet but satisfied since it's a reality.
