Your wish is my command
Complete | Sagold | 2000 released
The last chapters, after ch65 are getting pretty interesting. It's kind of the redemption arc of the ML, since Chinwoo doesn't remember the "other life" with him being a magical boy with Sunny, the loss of his parents, and all (because his wish got granted = making Hwan happy or wtv). Hwan at first searched for him but gave up, thinking he never saw Chinwoo so happy before. But they met again and this time Chinwoo is the one who hit on Hwan. Of course there are differences, since Chinwoo grew up differently, he is more stable and healthy in his head.
