Read manhwa Endless Summer / 엔드리스 서머
“I shouldn’t be doing this to you…”
Ryu Jin-han, her brother’s best friend who she met by chance.
Hiya Yeon, who witnessed her boyfriend’s affair with Jin-han, was happy for a moment.
After that, Ha-yeon strangely showed an unsightly appearance whenever she ran into Jin-han,
but at some point, he began to care
about her as a woman, not as his friend’s younger sister.
