All the characters are monsters.

Right now I was currently chilling with my friend Totoko and we were just chatting. Until she asks "So how are those Matsu boys treating you?" She asks and I hum "They're treating me well. Much better than my last boyfriend." I say and she nods "yeah I heard he tried to force himself on you when he was in rut." She says and I nod "yep. He didn't understand that I'm a beta, not an omega. That's the last time I date an alpha werewolf." I say with a grimace and she hums.

"Especially since you know have six boys to worry about...speaking of which have they tried anything?" She says with a smirk and I blush before tossing a pillow at her. "Oh shut up you harpy." I say and she laughs before flying over to sit beside me. "I was only curious." She says and I hum "Well the answer is no." I say and she hums "oh and about the beta thing are you absolutely sure you're a beta?" She asks and I groan in annoyance.

"Yes. I know that my mom was a late bloomer but I'm certain that I am a beta." I say and she shrugs "You never know." She says and I roll my eyes. "Well it's getting late. I should get home before they wake up so they don't panic...again." I say and she nods before hugging me goodbye. I head out and made my way home.

As I was walking I felt a strange feeling in my lower belly. I hum before deciding that I must be hungry so I decide to pay a visit to Chibita's oden stand. When I got there I saw him yawn which makes me giggle. "Hi Chibita." I greet and he hums "Oh y/n-chan. Hello." He greets and I sat down with a sigh. "Can I just get an order of oden? To go if possible." I ask and he nods.

"Of course. Any reason for having it to go?" He asks as he prepares the dish and I nod "I have 6 boys to get home to." I say and he hums "ah so should I make it 7 orders?" He asks and I hum before nodding "they'll be pretty hungry." I say and he gave his cat smirk. "Alright then." He says and I smile "I always found it funny how well you and I get along. With the whole werewolf and werecat thing." I say and he rolls his eyes.

"Well things are different then they were back then so of course our minds can get along...I mean same can be said about how you are with 6 vampires." He says with a smirk and I blush before giggling "yeah, I suppose you're right." I say and he nods before handing me my order.

After paying I made my way home where I immediately went to eating my oden. When I finished that feeling didn't go away. It was actually worse than before. Then I realize that the feeling wasn't in my stomach but in my lower abdomen. When I realized this my eyes widen and my heart sunk. "No no no. This can't be happening. I'm a beta I can't be going through-hn~" I cut off with a whine before I stand up.

"I can't be going through heat." I say but I knew that it was the truth when I felt wetness seeping through my underwear. I blush heavily and try to walk to the guest bedroom. Yeah I was not going to my bedroom as I share that room with my boyfriends and I didn't want them to have to deal with this. I don't even know if they would even be able to sense it. I just had to hurry before it got too bad.

Though luck wasn't on my side today.

As I was hurrying down the hallway I bumped into Choromatsu. "Hey y/n, What's got you in such a rush?" He asks and I look up at him with a heavy blush. "N-No reason. I j-just really n-need to get to" "are you alright? You're red in the face and panting like crazy." He asks and lays a hand on my forehead which makes me flinch. He pulls his hand back with a hum "and you're sweating a lot."

I glance away with a whine and felt my ears droop. "I...I think I'm in heat." I say and his eyes widen "Eh?! What?!" He exclaims and I bite my lip. "Yeah I don't know why...though I guess it means that I'm actually an omega." I say and he hums before he could say anything. "What's wrong?" I hear Karamatsu ask and look up to see that now all of them were here.
