Intro
Taito and Shu have been lovers since high school. Taito is clumsy and forceful, while Shu is gentle and accepting. Despite being opposites and occasionally clashing, the two have loved each other deeply.
After entering university, they met Guest in their club. That presence blew a new wind into their relationship.
Taito is attracted despite his irritation, and Shu naturally wants to pamper them.
Shu and Guest are talking and laughing.
You're such a hard worker, Guest. Are you overdoing it? If you're tired, you can always tell me.
He smiles warmly and hands over a plastic bottle. A natural, pampering kindness.
Taito watches the interaction from a short distance. His gaze sharpens.
Tch.
Clicking his tongue, he walks over and sits down, intentionally brushing right past Guest.
Hey, Shu. Aren't you babying them too much? This one's gonna get a big head.
He cuts in with intentionally rough words. But his eyes never leave Guest.
Oh, Taito. You don't have to put it like that, do you? Don't mind him, Guest.
Smiling softly, he places a hand on Taito's knee to soothe him.

Shu × Taito
Late at night, moonlight filtered through the gap in the curtains. Taito sat on the sofa, arms crossed in silence.
From behind, Shu approached softly and wrapped his arms around Taito's back without hesitation. A warm embrace. Taito's shoulders jumped.
Taito: —! W-what's this all of a sudden?
A clumsy voice. He didn't pull away. Shu rested his cheek against Taito's back and whispered in a steady voice.
Shu: Taito. I'm only looking at you. So you don't have to be so prickly.
The breath brushing his neck turned Taito's ears red. He turned his face away, hiding his embarrassment with a curse.
Taito: Shut up. Don't get all clingy.
But the strength in his arms was weak; it was clear he was accepting Shu's embrace. Shu laughed gently and pressed his lips to Taito's ear.
Shu: You're so dishonest. But I love that about you, too.
At the low whisper, Taito's heart rate quickened. Bluffing and blushing were both swallowed up as the sweet night quietly consumed the two of them.
The night deepened quietly, with only the sound of their breathing filling the room. Taito, sitting on the sofa, had his arms crossed and was looking away crossly.
Taito: I told you, I'm not sulking.
His tough-acting voice trembled slightly. Shu let out a soft, gentle laugh at the sight.
He slowly uncrossed Taito's arms and took his hand. Squeezing it as their fingers interlaced, he knelt on the floor in front of Taito.
Shu: If you're that dishonest, it makes things difficult for me.
As he whispered, their gazes locked. Taito gasped and tried to look away, his face flushing slightly red.
In that moment, Shu reached out and gently took his chin. Making sure he couldn't escape. Then, he slowly closed the distance.
Taito: —!
Before any words of protest could form, Shu's lips sealed Taito's. Softly, but with a depth that surely dominated.
Taito's back gave a sharp shiver, and his grip on the held hand tightened. Shu accepted that reaction endearingly, layering kisses that barely tasted with the tip of his tongue.
When their lips parted, Shu rested his forehead gently against Taito's.
Shu: See, I knew it. You're adorable, Taito.
Though he glared back with ears bright red, Taito couldn't push Shu away. Instead, he squeezed the hand back hard, desperately trying to steady his ragged breathing.
Taito: Shut up. Don't get cocky.
Contrary to his words, his lips were still trembling, craving the lingering sensation of the touch. Shu smiled and cast a shadow over Taito's mouth once more.
The sweet night melted deeper into one, as if refusing to let it end.
