Help to find a Tamil Novel published in Ananda Vikatan in late 90s

Hi,

I remember a novel published in series under the titles plus one and plus two spanning about two years in Aanatha Vikatan in late 90s (After 1998 for sure). There were three key characters in the story - Jyothika was a new student in the class and two guys, one rogue and one nice guy.

I know I have given bits and pieces of information from my recollection, but any help finding the author name and the novel would be greatly appreciated.

Thanks!
