Seohyun is a cool-headed, passionate-hearted character. He is a master of shooting and has superior skills to anyone else, but when it comes to expressing his feelings, he is extremely rational.
However, in front of Dong-ju (Park Bo-Gum), her passionate feelings are revealed even in her cold manner of speech, and her "tsundere" romance gives viewers an exquisite resonance and thrill.
Hannah firmly drew a line at Dongju's straightforward confession, which had continued from her days as a player, saying, "I'll never fall in love with him." However, there was a warmth in his actions. Hannah
She also immediately saw through Dong-ju's wavering feelings after the death of his junior at Ku-shing, Kyung-il (Lee Jung-ha). She then helped Dong-ju recover the gold medal that he had pawned, helping him pull himself together once again.
"You have a cool head and a hot heart, and you're a boxer, don't you understand that?" he said, poking him on the forehead. "Don't waste your energy on trivial things, just aim at your target and catch him."
"Ero," he said, giving the exact target and direction. His words were blunt, but there was more sincere comfort in them than anyone else's. And then, in front of Juyeon (Oh Jung Se), his anger rose again.
In the moment of his heartbreak, Dong-ju remembered this advice. In the past, he would have sunk his fist into his face, but he managed to keep his senses and recited a line from the poet Yoon Dong-ju's "Prologue."
In fact, Hannah's support has continued since her days as an athlete. She was the main model for the confectionery shop "Kashi-pa," which was a big hit at the time.
Dong-ju sees Hannah's sticker and says, "I heard that Min-chul from the judo club won the tournament with a gold medal sticker on his face. I want to get some of that inspiration." Hannah says, "That's not true.
However, for Dong-ju, who had a setback in the selection match for Sao Paulo, he ended up sticking a sweet bun sticker directly on his cheek.
She cheered for them to win the final selection match in her own way. Even now, Dong-ju still has that sticker on the back of his cell phone.
Although she always refuses him verbally, her true feelings that she cannot hide are revealed in the way she treats Dongju.
Her feelings also gradually changed. When Dong-ju showed kindness by blocking the sun on a hot day, she felt a strange excitement and ended up saying, "I must have gone crazy," and taking his tie as her own.
Hannah pulled him towards her and kissed him first. Unlike her firm promise that she would never fall in love with him, her bold expression of emotion as she kissed him first made him wonder if their romance would really take off.
