Deep Love: Regret

[Lightning protection ABO setting + dual male protagonists + BE + dog blood] Double A may not be very cool, but it must be very painful! "Asang... I'll take you home!" "Where did we come from? Mister, why don't you forget? Why don't I help you reminisce? I, Ji Sang, was just... Young and naughty. I fell in love with Mister, and I have been your companion for seven years. I can pick it up and put it down. I was originally going to marry you. Now I am tired and want to end it, okay? A substitute? Let me be someone else's substitute? Is he worthy or you? Mister, you think too highly of yourself, these seven years are really disgusting!" It's really bloody, if you don't like it, don't criticize it, it's easy to avoid the thunder, the plot is simple and clear, the person I love doesn't love me back. I love you, you love him, he loves him, but he loves me; very doggy, right? What's even worse is that when you realize you've fallen in love with me, I'm sorry, I don't need you anymore.
