When you moved into that small, creaky apartment building on the edge of town, all you wanted was peace and maybe five consecutive hours of sleep that didn’t involve your two-year-old climbing your face.

What you didn’t expect was your new next-door neighbor: a six-foot-four wall of muscle, tattoos, and mystery who introduced himself simply as

“Simon.”

You later learned the rest Lieutenant Simon Riley, Task Force 141. Military. Stoic. Quiet. The kind of man who looked like he could bench-press a tank and had probably done it.

And somehow, your toddler decided he was his new best friend.

The chaos began one Saturday morning when you were folding laundry and Milo decided to go on a covert mission of his own. By the time you noticed the front door open, it was too late he was gone.

You sprinted down the hall, heart pounding only to find Milo standing in Simon Riley’s doorway, chubby fingers wrapped around the man’s leg while holding up a juice box.

“Juice?” Milo offered solemnly.

Simon stood there in full sweatpants-and-t-shirt glory, mask still on from God-knows-what training, blinking down at your son like he’d just been handed a live grenade.

“…Uh. Cheers?”

You were mortified. “I—I am so sorry—he just—he likes—juice diplomacy, apparently!”

Simon’s shoulders shook once. You thought he was irritated. He wasn’t. He was laughing. A small, rough chuckle that you’d later come to crave.

From then on, it was chaos. Milo started inviting himself over for “missions” (which apparently meant pestering Simon into playing with toy cars). You’d catch the hardened soldier sitting cross-legged on the floor, a plastic fire truck in one hand, trying very hard to look unimpressed.

“Not a word,” he’d warn you when you grinned at the sight. “Wouldn’t dream of it,” you’d say while snapping a photo anyway.

But something shifted quietly in those afternoons. Between Milo’s giggles and Simon’s soft, reluctant smiles, your little world started to feel… safe again.

Then one evening after Milo had fallen asleep on the couch mid-cartoon you found yourself standing close to Simon in your dim kitchen, the hum of the refrigerator the only sound between you.

He reached out, brushing a stray strand of hair behind your ear, his voice low, husky with something unspoken.

“You’re gonna make me fall so hard I can’t get back up.”

And just as his lips brushed yours

“NOOOO!!”

Milo’s cry ripped through the room. Both of you froze. The toddler had woken up and was glaring, cheeks puffed, tears welling, tiny fists trembling with pure betrayal.

He stomped once. “No kiss Mama! She MINE!!”

Simon blinked. “…What?”

You tried oh, you tried not to laugh, but you lost it the second Milo marched over, climbed between you like a tiny bouncer, and threw his arms around your neck.

“No kiss kiss! No big kiss! No nuffin’!” he declared, sniffing dramatically.

Simon raised both hands in surrender. “Alright, soldier. Message received.”

You grinned over Milo’s curls, eyes twinkling. “Guess you’ll have to win him over before you win me.”

Simon huffed, gaze softening. “Challenge accepted.”

And somewhere between the spilled juice, bedtime songs, and toddler tantrums, the Lieutenant who thought he’d seen it all realized he’d just met the toughest mission of his life.
