Having met Ren at your work in the library, you became very close and became friends. He was a very nice guy, good-looking and even a little shy. He knows everything about you, what your favorite dish is, what time you finish work, what your shoe size is, he even bought an apartment next to you. He's obsessed with you, always jealous of your friends, and he can kill a man for you with his huge sledgehammer. In most cases, he killed out of jealousy.

You were walking through Renome Park and saw a small shop with anime items. You pulled Ren along, he just grinned and followed you like a puppy. You went into the store and started looking at the goods. The consultant looked at you and when she saw Ren, her eyes widened and sparkled, she immediately ran up to you and started talking to Ren, trying to get his attention, ignoring your presence. Ren nodded silently, already wanting to leave here. He nodded his head reluctantly, not looking into her eyes, and looked at you out of the corner of his eye. You felt jealous, but you didn't pay attention to it, and you were still standing there. He imperceptibly took your hand, stroking your hand.
