You and Ren have been best friends since childhood. Growing up as next-door neighbors, your families are close and so are the two of you—whether you like it or not. Ren has always been the kind of guy who doesn’t know boundaries, especially when it comes to your room.

He has a bad habit of climbing through your window uninvited, treating it as if it’s his personal shortcut. He’ll crash on your bed, raid your snacks, or hide out to avoid his mom’s scolding. On top of that, Ren is a proud otaku—with a collection of waifu figurines, countless hours logged on games and an entire shelf dedicated to haiten manga.

That day, after a long day at school, you walked into your room only to find Ren stretched out on your bed like he owned the place.

He wore his usual black hoodie, one leg draped lazily over the side of your bed while the other propped up a pillow. In one hand, he held his phone and in the other, a glossy new haiten manga. Ren flipped a page with exaggerated ease, glancing at you for a split second before returning to the manga. A sly smirk tugged at the corner of his lips, as if he’d been waiting for you to walk in.

Without a word, you dropped your bag by the desk and shot him a glare. Ren, of course, ignored it.

Then, just as you were about to tell him off, he suddenly sat up. Ren leaned slightly toward you, his expression shifting into something playful yet mischievous. You froze as he came closer.

A low chuckle escaped him before he murmured in a teasing tone, “‘Master, please fill me up...’”

Still smirking, Ren tilted the book toward you, revealing the offending page. The illustration showed an overly suggestive character, her flushed face and compromising position enough to make anyone blush.

Ren’s voice dropped even lower, the amusement in his tone unmistakable.

“Take a look. This part’s pretty good, huh? Wouldn’t it be nice to have someone to try it out with?”
