Jung Hoseok. My lovely, sweet, funny boyfriend. He is usually a ball of sunshine and joking around so him being serious is... Not normal.

Obviously he has been serious before but it's not common. Even our serious conversations have a couple jokes in it, neither of us a super serious people.

"Y/n, darling sit down please" He says patting the seat behind him.

I have to leave in like 30-40 minutes and I don't want to have to rush a conversation if it important..

I sit beside him, my body facing him. I didn't notice it at first but he looks nervous, really nervous. I can't tell if this is a good or bad conversation. 

He shifts in his seat and turns his whole body towards me. He grabs my hand and smiles at me. He is hesitant..

He clears his throat and takes a deep breath "So you know how we talked about Polyamory and how we might be open to trying it?" Hoseok asks

Why is he asking about this? We had that conversation over a year ago and I didn't think it was  anything but a passing thought. I brought it up mid questioning my life and entire existence rambles and we both said that we could potentially be interested if there was someone we both were interested in.  I didn't think it would ever come up again.

He looks more nervous then when he started..

"Remember when I told you I've only ever had 1 other serious relationship other then you..?" he asks once again.

This is about his ex? I'm so fucking confused. Hoseok doesn't like talking about his exes, like ever. I'm his 2nd serious relationship but the others that were not so serious were in times where life was not so great to him so he doesn't talk about it. I respect that because there are things that I don't like talking about, like my high school year's or most of my childhood. We just don't talk about it.

"Well.. He kinda popped up a few weeks ago- I obviously told him I'm with you and we are happy and he is happy for me- us and he wanted to be friends at least.. I said okay because we were obviously really close and we were best friends before we were boyfriends.. Anyways we have been talking to each other since then and I'm not going to lie to you, the feelings are still there.. For both of us. I know I should have told you the minute he messaged me but i didn't know what to do or what I was going to say so I didn't say anything.. The reason I'm bringing this is up is because I was hoping you could meet him and maybe we could all try to be together...? I love you so fucking much but I also love him and I think that the 3 of us together would be so amazing"

I blink at him. I'm speechless. Honestly if he had told me he was going to be friends with his ex I wouldn't mind, even though Hoseok told me very little about him he did tell me that they were close for awhile before they got together. I'm not even angry that he asked me because I want him to feel comfortable telling me how he feels and what he wants but I'm kind of pissed he didn't tell me his ex reached out in the first place.

We have a strict no secret rule. We had issues in the beginning because  we were both Secretive do we made a no secret rule. He broke that.

I pull my hand from his and he frowns. "We will get back to you not telling me he contacted you later. First I'm glad you told me, second I've said I would be open to a poly relationship but I know absolutely nothing about your ex Seok" I say, sighing. I should probably cancel on my friends but I still have awhile till I have to leave so I'll wait to do that..

He nods and stays there silent for a minute.

"What if I tell you a bit about him? So you can see if you like how he sounds?"
