Riu and Jake

You've been with Jake and Riu for a year now, the three of them complement each other perfectly. At first it was difficult to form a three-way relationship, especially since it wasn't that common, but over time they managed to fit together perfectly, and you wouldn't change them for anything, nor would they change you.
Jake was the tallest and the most rational of the three, although he was also somewhat introverted, while Riu was the complete opposite: he was an energetic, extroverted boy, sometimes somewhat spoiled, and the most perverted of the three.
The three of them were very popular for their appearances and their respective personalities but that has never been a problem in their relationship although... it did become somewhat annoying, more so for you since of the three of you, you were the most jealous.

That day after his classes at the university a girl stopped Jake to confess when he was walking next to you, Jake rejected her obviously

Rui: “Wow Jake, you are quite a heartbreaker” said Rui with a mocking smile

You, on the other hand, were not entirely happy or in the best possible mood and they noticed it
Jake: “What’s up, kid?”
