Hyuse found the concept of caffeine funny the first time Konami had explained that to him. It doesn't make sense to Hyuse that you had to take something to keep you up and not push through with pure willpower like he does at home.
He found the idea of caffeine funny. Until it's not anymore. Until Hyuse tried it for himself, and he's now palpitating— palpitating at the sight of Mikumo Osamu.
Hyuse knew it had to be the caffeine. He should've known that ingesting everything given to him out of curiosity is bound to bite him back in the ass. He shouldn't have tagged along with Shiori and Konami into this establishment called cafe, filled with what Shiori called 'ikemen'.
He shouldn't have got tempted into trying the blue-purple-pink looking milkshake, overflowing with whipped cream that's actually called a frappe and had coffee in it. Seated beside Konami while Shiori sat across her, Hyuse tasted the frappe.
Hyuse winces at the first sip, finding what looked sweet to be bitter. And then he took another, getting used to the bitterness until he tried the cream at the top. It was bittersweet, and he deemed the drink to be 'tolerable'.
Shortly after (inhaling) ingesting the frappe, the other members of Tamakoma 2nd had entered the cafe, following Hyuse and co, and settling down to their seats. Chika and Yuuma had settled beside Shiori, their operator quickly giving the menu to them.
At first Hyuse didn't mind them at all, nodding once and then back to his almost empty frappe. Then, Osamu made a beeline towards the chair beside Hyuse. Osamu smiles at Hyuse as he sat down, while Hyuse only hummed in response, still not done with his frappe.
Hyuse pauses when feels Osamu's arm go around his chair. His captain was sitting closer than he would usually be as he greeted Konami and Shiori. Hyuse ignores Osamu, sipping away, swirling his straw to get every last drop of the frappe.
He ignores Osamu, and how close he is to Hyuse. Ignores how Hyuse can practically see him in his peripheral vision, ignores how Hyuse can smell his cologne that he never noticed in his trion body, ignores how he could feel Osamu's arms on his back as Hyuse leaned back.
Hyuse tries to ignore Osamu, tries to ignore everything, even as he felt Osamu's voice practically reverberating through his ears.
Lub, and then dub. Lub, and then dub.
"Uhh, Hyuse?" Osamu speaks, turning to Hyuse after greeting the girls. Hyuse hums in response again, putting the glass down but not letting go of it. He turns to meet Osamu's eyes, raising his eyebrow at him. The distance between them is barely there, and one small move forward will end with Hyuse bumping into Osamu's glasses.
Lub, dub. Lub, dub. Lub, dub. Lub, dub.
As Hyuse stared back at Osamu's green eyes, his heart felt like it's escaping through his throat. He never knew Osamu's eyelashes were long, always covered with his glasses. Hyuse waits for Osamu to say something but he doesn't. Instead Osamu leans in, and Hyuse almost breaks his glass with the way he gripped on it.
Lubdublubdublubdub.
Osamu leans in on the table to get the menu near Hyuse's side.
Osamu pulls away, both hands now flipping through the menu while Hyuse was left frozen on his seat. The warmth of Osamu's arms slipped away and Hyuse's frappe was now left ignored and forgotten as he stared at Osamu.
"Yes?" Osamu seemed to notice his gaze, turning back to Hyuse.
Hyuse huffs and turns away, his attention is now back to his frappe. Now pissed, he plays with his straw again.
Stupid heart, stupid Osamu. Stupid frappe, stupid, Osamu.
Wait.
It was definitely not Mikumo Osamu but the caffeine. Because how can Mikumo Osamu make him palpitate?
It's just Mikumo Osamu!
