Burn Your Heart for Me

Miu has a crush on her older childhood friend and next-door neighbor, Ran. On the other hand, Ran's younger brother, Ren, is flashy, a huge flirt, and totally not boyfriend material—at least, that's what Miu thought. But lately, he's been showing up when she's in trouble, saying things that make her heart race, and throwing her feelings into chaos. Why is he affecting her so much now!? However, Ren's true nature is... way darker than she imagined—he’s the type who’ll use anything to make Miu his. A twisted love story with a dark party boy childhood friend!
