I just finished to watched it lately and its really worth watching for! You know, the feeling of being alone for a long time really makes you weird and really really lonely. Despite that Min Kyu is unbelievably foolish, maybe thats because of how desperate he was to have someone to  be his friend. I felt so sorry for him for having that kind of sickness and im very happy that because of Aji 3, he found his cure, his family and that he is no longer alone anymore! great great series to watch!!!
