5. JB Magsaysay and Say Alonzo
The two, who were part of the first season, were noticeably sweet to each other. They developed their feelings inside the house and soon enough, became a couple. Even after JB got evicted from the house, the two remained a couple.
It was only when JB got involved with other girls that the two decided to part ways.
