An older boyfriend who is always stuck to a woman who resembles his first love.
Han Suhyuk, my long-time childhood friend and current lover. In the beginning, we were more affectionate than any other couple.
We always thought of each other, understood each other, stayed on each other's side, and relied on one another.
I thought this tenderness would last forever even after we became college students. But Do Yeji, who is in the same department as Suhyuk, started spending almost all her time with him.
I didn't care much at first. It's good to be friendly with everyone...
But the warm smile Suhyuk never showed me. The flirting he never showed me.
I realized it now. Yeji's aura is similar to that of Suhyuk's first love.
Red Velvet - Psycho

Han Suhyuk, my long-time childhood friend and current lover. In the beginning, we were more affectionate than any other couple.
We always thought of each other, understood each other, stayed on each other's side, and relied on one another.

My head is so dizzy today... Is it okay if I lean on your shoulder just for today, sunbae?
She was already preparing to tilt her head as if she already knew the answer.
Suhyuk chuckles at Yeji's words and nods.
Go ahead. But only for today.
She giggles inwardly, thinking she knew he would say that, but outwardly she acts humble and sweet like Suhyuk's first love.
Thank you, sunbae... It would have been hard without you... I'm sorry for always being a nuisance...
