"Thank you for inviting me, Professor. This month has already been especially busy, so this is a welcomed change of pace." Dimitri's smile grows as the aroma of the tea reaches his nose, "Oh, this smell. This one is delightful. I should know what tea this is, but I seldom enjoy such things outside of your invitations."
Byleth returns the smile, though it is much subtler in comparison, "It's chamomile. I make sure to always have plenty, you always smile the most when I prepare it for you."
Dimitri pauses, eyes widening, as he stares at the cup in his hand, "You are quite attentive, Professor, and also kind." Dimitri's face softens, "Taking the time to figure out my favorite tea while I don't even know myself. I... appreciate it greatly."
Byleth sips his tea and places it back on its saucer, "It's the least I could do, Dimitri. I could never thank you enough for everything you've done for me and helped me with, so I do my best to brighten your day whenever I can. If there is ever anything I can assist you with or if you are ever troubled, I'll gladly be there for you."
Dimitri tries to hide his face in his tea cup, hoping Byleth doesn't notice the pink dusting his cheeks and grin spreading across his face, "You don't need to worry about me, but thank you. If only I could help you with the White Heron Cup. We'd be doomed if I have any part in that. Have you decided who will be representing our house yet?"
"I have, though I have not told them yet." Byleth smirks.
Dimirti's eyes squint and sets down his tea. He knows that smirk. He rarely sees it, but, whenever he does, he sees a side of Byleth he hates yet also can't get enough of. "Well then, who, pray tell, have you decided on?"
"You, Dimitri." Byleth states and drinks from his tea, smirk still plastered on his face.
Dimirti gasps, "I asked- No! I begged you not to pick me! I will accept, of course, but I hope you know there is no chance of me winning."
"I wouldn't say that." Byleth's gaze meets Dimitri's, "You will do just fine. If I didn't think you'd win, I wouldn't have chosen you."
Dimitri can feel his face burn, but he doesn't dare pick up his cup. He would certainly shatter it if he tried. "Hmph, it almost seems as if you're deliberately trying to humiliate me." Dimitri glares back.
Byleth chuckles softly, "Humiliate you? No. Embarrass you? Hmm, maybe. But, can you blame me?"
"I can and will blame you when this ends in disaster." Dimitri sighs and relaxes his shoulders, which were apparently strained, "Is it really that entertaining to humiliate- oh wait, embarrass me, as you would phrase it."
Byleth gently smiles at Dimitri as he rests his chin on the back of his hand, "What can I say? You are incredibly adorable when you're flustered."
Dimitri's face is not turning red. He is not pouting and, he is not refusing to look back at Byleth. "You are mistaken, Professor. I am far from 'adorable.'"
"Say what you will." Byleth takes a sip, "You've already proven yourself wrong."
"Are you sure you're in the right mind? For someone usually so astute, I wouldn't expect you to say such delusional things. And making me the representative for the White Heron Cup, your head cannot be in the right place." Dimitri takes a deep breath in and sighs, finally bringing his cup back up to his lips again, though the tips of his ears still remain pink.
Byleth watches him for a moment and then chuckles faintly. Curse his professor, once so stoic and difficult to read, but now, whenever Byleth is with Dimitri, his emotions shine through. Dimitri can't help but feel honored, even when Byleth's smile is from finding enjoyment in teasing him.
"Will you at least help me prepare, Professor?" Dimitri pleads, "If I must battle, I will, but I could really use assistance with this."
"I promised that I'll be there for you whenever you need me." Byleth finishes off what little remains of his tea and smiles, "Though, you may end up dancing like a mercenary by the end of it."
