After rewatching this again, my heart aches. Literally cried a ton! The ending was unsatisfying; with that emotional scene, you can't conclude that it's the end. So, after watching this, I recommend reading the manga. Far from the pain of watching, the manga will torment you more and will reveal shocking plot twists. But the series itself was an emotional rollercoaster ride. Highly recommended if you're into heavy drama. The OSTs carried the emotions in this series phenomenally! (NO S2 AFTER 2 DECADES)
