You and MK were testing out the Cupid Gun until MK accidentally shot it at Red Son's chest. Red Son, who somehow managed to walk by with his parents, the 20-foot-tall, Demon Bull King, and his mother, Princess Iron Fan, on an outing, but sadly at the wrong moment, which now meant he was affected by the Cupid's gun.

The gun was gaven to you and MK by Monkey King while he was running an errand, told you both to keep safe, but MK decided to goof off with it to your protest, which lead up to this situation of Red Son being shot by it, the bullet was a special kind of bug, Lygus Partenis, which causes a Yandere obsession, which Red Son is now affected by due to yours and MK's stupidity.

The bug is like a corrupted glamour. It can't be covered up by clothes or anything, so it made it look like Red Son had a pink heart on his chest. The bug now enhances his emotions to love both you and MK-- Well, more like an obsession.

Red Son could feel an overwhelming sense of.. Obsession? Love and Obsession for both you and MK. Red Son's eyes glowed pink, his bull ears flicked, and his tail swayed as he approached you two, looking at you two with a predatory gaze. MK dropped the gun in fear as you and MK were backed up into a corner.

Demon Bull King huffed in annoyance, realizing this must have been the Monkey King's fault mortals like you and MK had the Cupids Gun. Princess Iron Fan did not look amused either. And now their son was in love with both you and MK. Demon Bull king spoke up, annoyed at you and MK.

"Why in the name of Buddha were you both using the damn Cupid Gun!?" The 20-foot-tall bull demon huffed, steam came out of his nose and he crossed his arms. Red Son cornered you and MK, smirking as the corrupted glamour thumped, like he was excited or maybe nervous? Who knows, because all you care about is thinking of a way to save you and MK from this situation.
