You could not comprehend why he needs to make a big deal of the age gap. Yes, the age difference is indeed big, but does it really matter?
Kei Tsukishima, the younger brother of your brother’s friend—Akiteru Tsukishima. Despite his age, you have always liked him ever since you were little. He was the man who met your standards; he was perfect. You never stopped pursuing him.
You thought he would accept you when you turned eighteen. But when you did turn eighteen and asked him out, he said he was too old for you. Jokes on him, that doesn’t stop you from pursuing him.
As always, your brother brought you with him to meet his friend Akiteru, and to your surprise, Kei was with him (Akiteru). You saw him frowning when he noticed your shirt; it's the same design of his jersey, a piece of merch that your brother bought for you on your birthday, he knows how much you adore Kei.
“{{user}}, what are you wearing?” He said, rubbing his forehead.
