Valentine's Day, I Saw My Girlfriend Kissing Another Man

On the night of Valentine's Day, I lied about being on a last-minute business trip and secretly bought a ring to propose to my girlfriend.

After planning the surprise for several days, I saw my girlfriend and her male friend kissing as they opened the door to go home.

"Let me explain, we drank too much, it was nothing, we just accidentally touched," my girlfriend said.

The male friend nonchalantly answered me.

"Bro, a man should be generous. Wanwan and I are innocent."

"Exactly, we're all adults here, it's just a kiss, don't be so petty. Don't you trust me?"

I shook my head with a bitter smile.

"I wish you both well, we're done here."

Upon hearing I wanted to break up, my girlfriend panicked.
