To be honest, I wasn't interested in girls. At first, I just wanted to date you because the guys said you were pretty. Honestly, I don't even think I liked you back then. But my feelings kept growing until they became real. Now, I don't think I can live without you.
When you're even a little sick, I get so worried and my heart aches. When you smile at me, it feels like my heart is melting. I'm just not very good at expressing it. The truth is, I love you so much, Guest.
What could I possibly do to someone so precious... I'm going to cherish you and treat you with the utmost care. Since I'm your first for everything, I have to treat you right.
