PHI'S POV
   I watched as (y/n) left the castle again to meet up with this Rio kid. Not knowing who he is, I of course am skeptical. (y/n) leaves everyday to go meet Rio at this coffee shop. It makes me think that my beautiful girlfriend would be cheating on me. But she wouldn't, she's to pure hearted for that.
   Of course this happens right near my birthday out of all times. I want to trust her, she's immortal like myself so I can tell if she's lying to me or not. Nothing seems to be up. Then again she has been around for awhile as well so, she could be lying to me.
   I can't stand all of this stress with everything. When she comes back home I'm going to have to question her more intensely.

LATER
   (y/n) walks inside the castle, runs to me, and hugs me tightly and puts down her bag. I looked at her beautiful figure, but kept a strait face. Still on my mind about this whole Rio situation.
   When we finally pulled away from the hug I look at her strait in the eyes. "Okay (y/n), please explain to me what's going on with Rio."
   She looked a little shocked at what I said. Seems like she didn't think I knew about Rio. "Umm, I can't tell you what's going on between myself and Rio..."
   Now this upset me. Why wouldn't she tell me anything about this Rio guy!? "Look      (y/n), if there is something going on please tell me." I explained, trying not to get to upset and go into a fit of rage.
   "I really can't tell you Phi. I'm so sorry, can you wait until your birthday for the answer."
   I couldn't hold into my anger anymore. "No, I can't (y/n)! I know this has been going on for one month now! What are you waiting for? Are you waiting for my birthday to brake up with me?!" I yelled.
   (y/n) had a few tears in the brink of her eyes. She held it in and tried talking again. "I love you Phi, I would never do anything to hurt you." She said, walking closer to me and trying to comfort me.
   I took a quick step away. "No! Tell me what's going on between you and Rio!" I yelled a little louder.
   "I told you I can't Phi! I really can't. You can get all the answers you want on your birthday." A few tears streamed down her face.
   "Your cheating me aren't you!" I never thought those words would ever come out of my mouth to the girl I know I love.
   A river was flowing out of her eyes. "I-I'm telling the truth Phi! You've got to believe me." (y/n) pleaded.
   "No, I don't. All these signs show me that you don't care about our relationship." I stated. (y/n) ran to her room in the castle. I felt bad. Maybe she really wasn't cheating on me and I'm just being paranoid.
   Anyways, I realized she left her bag. I took her bag and saw that her phone was vibrating. Taking out her phone I saw Rio just texted her. 'Are the plans still on?' I opened up her phone and began to text back to him.

Phi: Hi! This is Phi, (y/n)'s boyfriend. Who are you, and what do you want with my girlfriend?!

Rio: Oh, so your the boy she's always talking about with the plans.

Phi: What plans?

Rio: I shouldn't be telling you this... but you will eventually find out during your birthday.

Phi: Oh get on with it already.

Rio: Well I'm a baker, and one of (y/n)'s close friends. She's been planning you a birthday party that's supposed to be a surprise. Well, not anymore due to myself being a bad secret keeper. Anyways she's been talking to me for a while because of the interesting cake she wanted you to make. She also wanted to ask help with the decorations.

Phi: I feel like an idiot.

Rio: Why? Did you do something wrong to (y/n)?

Phi: Yes, I did. I thought she was cheating on me... with you.

Rio: Ouch, well good luck with that Phi.

   I turned off (y/n)'s phone and was questioning what I'm going to do about the whole me yelling at (y/n) situation. Walking up to (y/n)'s room I heard her crying. Great! Now I feel even more horrible about what I did.
   "(y/n)? Can I come in?" I asked after knocking on her door.
   "*Sniff**Sniff* Why would you want to talk to someone like me." She replied.
   "Please let me in (y/n)..." I was on the brink of tears. Of course she wouldn't want to talk to me. "I'm so sorry. I didn't know what was going on and I got really skeptical." I rested my head on her room door.
   I heard some stifling and the door creaking open. Standing face to face with  (h/l) (h/c) haired girl. "A-are you really sorry Phi? Or are you just here to yell at me again..." (y/n) said looking down at the floor.
   "You left your bag with your phone back there. When your phone buzzed with the name Rio on it I texted him about what was going on. I'm so so sorry. I should've known that you would never do something like that to me." I ranted to (y/n), practically begging for forgiveness.
   I leaned in and engulfed my crying girlfriend in a hug. "I love you so much (y/n). You don't even know how much I love you. Please forgive me."
   She buried her head into my chest and said something that was muffled by my chest. "What was that sweetheart?" I asked.
   Her head shot up and she began looking into my eyes. "I forgive you." (y/n) said in her sweet voice.
   "I love you, I love you, I love you. Now how about we just relax for the rest of the day okay?" I asked then kissing her on the forehead.
   "S-sure Phi." I love when she gets so flustered, it's so adorable.
