Trying to find the movie name... plz help guys!

So i've been trying to find the name of this tamil movie. The plot goes like this: there are 4 murders that take place in the beginning of the movie and these four men are connected through their wives. The 4 wives were classmates in school/college (i don't remember) and one of the girls would have seduced this teacher of theirs, for all of them to get good scores in exams or something like that. But in the end, this professor gets to know that it was all a joke, and his wife decides to take revenge on these girls for humiliating her husband. She waits until they're all settled in life and then executes these murders. Please help me find the name of this movie, people!!
