Hachiman's POV
Hachiman: "So? What's up all of a sudden?"
Ardan: "Onii-sama, I'm angry. Do you know why?"
Hachiman: "No clue. Did I do something to you?"
Ardan: "…Not exactly. That's why I'm angry."
Hachiman: "That makes even less sense."
Mejiro Ardan's sudden "I'm angry" declaration has me stumped. I'm racking my brain, but I've got no idea what she's mad about. And she seems seriously pissed… What does she mean, I didn't do anything, so she's angry? Wait…
Hachiman: "Is it… because I still haven't scouted you?"
Ardan: "I've thought about that, but that's not the reason this time."
Hachiman: "Oh, not that… Then I'm lost."
Ardan: "…You really don't know?"
Hachiman: "If I did, I wouldn't be this confused."
Ardan: "…Fine, I'll tell you. Onii-sama, why didn't you consult me about your move?"
Hachiman: "…Move? Why's that a problem?"
Ardan: "…Do you remember our date last year?"
Hachiman: "Yeah, of course… Wait, you mean when you asked if I had no plans to move out of the dorm?"
Ardan: "Exactly. If you were seriously considering moving, I wish you'd consulted me… I could've found you a nice place."
Hachiman: "No way, that's not okay. Why would I ask a high schooler about where to live?"
Ardan: "I would've covered the costs…"
Hachiman: "That's even more not okay…"
Ardan: "That's why I'm angry, Onii-sama."
Hachiman: "I'm still not getting why this is worth getting mad over."
Ardan: "So, I'm staying at your place tonight."
Hachiman: "Wait, my opinion doesn't matter? Hold on, Ardan's not that kind of reckless Uma Musume, right? Your family wouldn't allow it."
Ardan: "I consulted my parents and grandmother, and they happily agreed♪"
Hachiman: "Happily agreed? What's that supposed to mean?"
Ardan: "So, Onii-sama, I'll be in your care today♪ I'll help with anything, so don't worry."
Hachiman: "I never said you could stay! And what about the overnight permission form—'I submitted it.' …I'm not approving this."
Ardan: "Is Onii-sama the kind of cold person who'd abandon his little sister?"
Dammit, she's dead-set on staying. Has her personality changed or something? Since when did she get this pushy? She wasn't like this before, right?
Hachiman: "Ugh… Fine, you can stay."
Ardan: "Thank you, Onii-sama. I'll be staying for three days♪"
Hachiman: "…Three days?"
Ardan: "Yes, three days."
Hachiman: "…My place isn't a hotel. One day's not enough?"
Ardan: "Onii-sama, I believe this is necessary for us. The more time I spend with you, the better. It helps us understand each other more. Isn't this a great opportunity for that?"
Hachiman: "That'd make sense if we both agreed, but I'm not on board."
Ardan: "My Onii-sama is a big-hearted person."
Hachiman: "You're mistaking me for some saint. I'm just a regular guy."
I tried to talk her out of it, but Ardan wouldn't budge. In the end, I gave in to a three-day stay. Ugh… I just want to eat with Rice for some healing. I need comfort, stat…
After School
Hachiman: "…"
Ardan: "Hehe♪"
Hachiman: "Uh, Ardan-san?"
Ardan: "Yes, what is it?"
Hachiman: "Why are they here?"
Ardan: "Pardon?"
Hachiman: "I'm asking why they're here!! I didn't hear about this!!"
Chiyo: "S-Sorry! But I've been curious for a while about what kind of trainer Ardan-san cares so much about~."
Yaeno: "I feel the same as Chiyo-san. Plus, I sensed no ill intent from you, so I decided it was safe to tag along!"
Hachiman: "Ardan, I thought it was just you. Why are Chiyo and Yaeno here? Did you leave that out?"
Ardan: "It's a surprise♪"
Hachiman: "I don't need that kind of surprise!!"
Chiyo: "Um, are we causing trouble? If we are, I'll go back…"
Hachiman: "…It's fine, Chiyo. You're welcome to come, no worries." pats head
What's with this girl? Those puppy-dog eyes! How could I say no? There's healing beyond Rice after all…
Ardan: "Onii-sama, could you do that for me too?"
Hachiman: "You kept those two a secret, so no pats today."
Ardan: "…Understood."
Yaeno: "T-T-T-Trainer-dono!?"
Hachiman: "What?"
Yaeno: "I-I submit that… head-patting is… a bit too close, don't you think!?"
Hachiman: "…Is it?"
Chiyo: "No, I'm fine! It actually felt kinda nice! Ehe~."
Ardan: "I'm jealous, Chiyo-san…"
Yaeno: "This 'blazing fire' in me… how do I contain it…!?"
…This is gonna be a wild three days.
