Technically 3 main couples one side couple, and throughout the story there appear other very minor couples that don't have their own stories.
1st couple 1-65
2nd couple 66-102
3rd couple Ch 103-174
side couple Ch 175-end (+ I think 2 chapters earlier about them, somewhere in the middle of the 3rd couple story, don't know exact chapters)

Can someone tell me how many couples are in this manga and what chapters cover each couple?
