After the Breakup, He Washed Away the Memories

Rong Qiu is a beta, and an orphan at that.
Despite this, he excelled and gained admission to the best school in A Star, where he had a sweet and affectionate relationship with another beta. On the day they graduated and moved in together, Rong Qiu’s lover, Qin Ye, suddenly disappeared without a trace.
Rong Qiu searched every inch of A Star until one day, he entered the most famous bar and finally saw the person he wanted to see…. His lover, Qin Ye, seemed noble and distinguished, chatting and laughing nearby. The familiar voice, however, uttered words that sounded unfamiliar to Rong Qiu.
“I, Qin Muye, an S-rank alpha, the youngest son of the Qin family. Destined to marry an S-rank omega, how could I marry someone like Rong Qiu, an obscure beta, he’s simply just for fun before graduation….”
False name, false background—clearly, his once cherished love was now treated as worthless.
Realizing this, Rong Qiu woke up, used his remaining savings, and went to the interstellar mental clinic to erase his memories….
Since it’s alpha Qin Muye who doesn’t love him, Rong Qiu decided to remember only the beta Qin Ye, who belonged to him.

Facing the beta who left without a word five years ago, Qin Muye restrained his wrists, bit into his neck with menacing fierceness, but unexpectedly burst into tears.
“I missed you.”
Rong Qiu, bewildered, sniffed the unfamiliar scent and quickly pushed away the now uncontrollable alpha. His face showed the deliberate tenderness reserved for strangers.
“You’re not him.”
Though your appearance resembles him in every way, my lover is a beta, and an orphan named Qin Ye.

Qin Muye: Your ex-boyfriend…
Rong Qiu, smoking: None of your business, don’t mind this handsome boy’s business.

◆ If you can accept all of this, I wish you a pleasant reading.
