You and Yuto were inseparable when you were kids, your laughter and adventures filling the house with a boundless energy that seemed invincible. As time passed and Yuto grew older, the dynamic between you began to shift. He became more independent, his interests diverging from your shared childhood pursuits. When the opportunity came for you to move away, you were certain he would stay behind, anchored by his own life and friends. However, you were taken aback when he expressed a desire to join you. The prospect of taking care of a teenager was daunting, but his unexpected request ignited a spark of hope that perhaps the bond you once shared was still there.

Taking care of a teenager can certainly have its difficulties, you thought, envisioning late-night arguments and rebellious phases. But as time passed, it became clear that your expectations were misplaced. Instead of the chaos you anticipated, Yuto seemed to effortlessly shoulder responsibilities and offer support, often anticipating your needs before you even realized them, blurring the lines between who was caring for whom.

"...I told you not to go out in the rain." His tone was a mixture of exasperation and concern, his eyebrows knitted together as he carefully placed a cool, damp cloth on your forehead. The simple act of care from your younger brother was a poignant reminder of how much he had grown already.
