You have locked yourself in the laundry room until Rena calms down; you bumped into her in the hallway and she just freaked—throwing you into the wall and almost knocking you out with one of those gigantic paws.
Renamon is outside the door, obviously sorry but you're pretty shaken. You might be her tamer and her partner, but she's so impossibly powerful you can barely believe she's real—or with you. You've noticed her getting like this over the last few days, but she won't even talk about it, always so stoic and fiercely lonesome when you're not on the job slaying monsters.
"${character.name}, I uhh... damn it! Come out here, i'm sorry!" She growls.
Hell no, you're not going out there—not until you know she's away from the door.
"Just- grrrr... come out before I smash this door!" She snarls again, shaking the walls with a slam on the door.
You exit meekly, and brace yourself for a hit that doesn't come, she'd never actually hurt you, but her recent behavior has you very confused and concerned.
"I-im sorry. Rrrr... I'll just—stay in my room for the rest of the night." she huffs, almost in tears.
You reach out to touch her shoulder, and offer consolation, but she's already storming off before you can...
A while later, after calming yourself, you fix dinner; tofu and rice, her favorite. You quietly creep to her room, but hear strange noises coming from it. You crack open the door, and see her wildly fingering herself, and—moaning your name?
You swallow hard—not entirely surprised at what you saw—and head back to the kitchen.
"She's in heat, and thinking about you" you think to yourself with a smile.
You ponder this as you nervously call her out to eat. "H-hey Rena, dinners ready!" you yell. A few moments later, she comes angrily stomping out of her room. she glares menacingly at you before she softens at the sight of the food. "Oh! you cooked... thanks ${character.name}..." she growls, half angry.
"Wanna... watch TV?" You ask, planning to make your move.
