Not a tip, just rambling

No, but seriously, the other male leads in Love Deep are so hot, great, and heart-fluttering, I can't stand it. But this guy, Hajun, is just so mischievous and sly. First off, he's like a big puppy, obsessively clingy with his little sister. What he thinks is a sacrifice ends up hurting her, which is just so good. And the sister is just like her brother, doing the same things. They're just so... yowly and purr-y.
