Played for Five Years, I Marry Into Billions Instead

I decide to propose to Rebecca Milton, now that we've been in a relationship for five years. But I end up overhearing her conversation with her childhood friend, Tobias Wright, outside a private room in the clubhouse. "Seriously, Rebecca? Are you still hooked on the idea of pretending to be a poor student? All this just so you can win a bet of wooing Sebastian Grant, the business genius, and making him yours? "The Grants are on the verge of filing for bankruptcy. Heck, Sebastian has also cut ties with his family just so he can be with you. Don't tell me you seriously plan on marrying him!" Every cell in my body freezes upon hearing Tobias' words. Then, I hear Rebecca responding to him flippantly. "Marry him? As if! All I have to do is wait for him to propose to me, then I can expose the truth of the bet to him on the spot! Oh, the expression he's wearing must be amazing!" Tobias chuckles lightly in return. "You are in a five-year relationship with Sebastian at the end of the day. Are you sure you don't have feelings for him?" Rebecca scoffs back. "I was just playing with him, you know? Whoever puts their heart on the line loses this game." Then, she gazes at Tobias tenderly. "Don't you know very well who I'm truly in love with?" It turns out that the girlfriend I'm head over heels for, as well as the relationship that I view as my prized treasure, is nothing but the product of a bet. I call my parents on the spot. "I will go along with the marriage alliance."
