MTL - My Wife Is A Princess - v3 Chapter 399 Vinegar jar

After his parents died, Alex Roth had a plan: become a wizard. Through hard work, he was accepted into the world’s greatest university of wizardry—but fate had another plan.

But who would have thought that before the two could even get into a fight, the girl took her girlfriend’s hand and actually came out of the closet in front of them? The two straight men, who had been at loggerheads for three months over the girl, had their three worldviews shattered.

The two enemies sat down to drown their sorrows in alcohol and in the confusion, somehow together in bed.

Afterward, Jiang Xiu got up holding his almost broken back. His mind exploded for half a minute, and he resolutely decided to forget about it.
