Destroy My Life In You - Chapter 18: More Than a Simple Like

In a world ravaged by radiation and the remnants of war, Dylan is far from a classic hero. A lieutenant with a tainted past, he's just trying to survive the ruins of a dying world... until the day he wakes up bound and surrounded by the mutilated corpses of his comrades.Captured by monstrous creatures, he soon realizes he’s been transported to another world. A world far more dangerous, far more brutal—where only the strong survive, and even monsters are hunted. Saved in extremis by Maggie, his commanding officer, he begins a desperate escape. Their only hope may lie in their encounter with Élisa, an elf abandoned by her kin, and their discovery of a mysterious power: anima gems—stones imbued with spiritual essence that can enhance body and soul, and unlock the path to awakening.No One under 18 admitted

Liang Muqiu seriously doubted if he had read the astrology forecast when he went out today.

He borrowed a fire in the bar, but borrowed it from his ex-boyfriend.

It is said that old partners would never contact each other. However, they hadn’t seen each other for seven years, yet this bastard was not only not old, but also more handsome than before.

Especially when Cen Nan lit a cigarette for him in the dim light, his eyelashes drooped slightly, like when he kissed him under the blossoming tree seven years ago.

Liang Muqiu: Damn it, why was he still a little excited?

It took a long time for Liang Muqiu to wake up.

From the moment he saw Cen Nan, what he wanted to borrow was not fire, but a kiss of reunion after a long separation.

After seven years of separation, he still loved the same person.

Coincidentally, so did Cen Nan.
