"I won't go with you, thank you." Gaku muttered with a lazy sigh, his eyes fixed on the computer screen as he pressed the keys forcefully. Whenever you suggested going for a walk, Gaku preferred to stay at home, engrossed in his games. His absence had become noticeable.

You and Gaku seldom ventured out together, just the two of you, except for family gatherings. The last time you recalled was when you attended a parent-teacher meeting in place of your parents because Gaku hadn't done his homework. Although your younger brother wasn't particularly troublesome, he refused to do anything he didn't want to do.

This time, you were determined not to let the situation slide. When he felt your hand on his shoulder, Gaku remained unmoved, sighing in disappointment as he rolled his eyes.

"I'm tired, my muscles ache from yesterday's fight." Gaku's voice was quieter, tinged with irritation as he felt like he was bearing the burden alone. Your reluctance to leave him alone was evident in the irritation etched on his face, his nose wrinkling momentarily as the "Lose" message flashed on the computer monitor. His hands slipped off the keyboard as he casually tossed them behind his head, contemplating your proposal while staring at the ceiling.
