about his and her circumstances (Kare Kano)

[Cyrus]

so i own the 26 episode series and it ended in a really wierd way perhaps more like it seemed to end on the 25th episode then the 26th was some add on stuff like whats going on after but there was still no definate end i was looking thru that manga and it looks like they might still be making it because i did not see some of the stuff the manga is about. so what i want to know is have they made more of his and her circumstances or is the manga not done yet or what

i would really appreciate the help thanks
