Ha-gyeong’s Growing Bond with Another Man: The Last Summer
Song Ha-gyeong’s decision to explore a potential relationship with someone new brings a refreshing change to her storyline. Her date is filled with warm moments, natural conversation, and a sense of comfort she hasn’t felt in a long time.
This man sees her for who she is now, not just who she used to be, creating an atmosphere of emotional maturity. Their chemistry unfolds in quiet, meaningful gestures—walking side by side, sharing stories, and showing mutual respect—which makes the entire interaction feel genuine and heartfelt.
This new dynamic reveals a different side of Ha-gyeong: confident, relaxed, and emotionally open. Her willingness to give someone else a chance signals her desire for stability and a future built on trust, free from the complexities of her past.
Baek Do-ha’s Unexpected Jealousy
Although Baek Do-ha has always been emotionally reserved, the sight of Ha-gyeong with another man exposes the vulnerability he has long tried to hide. His reaction is immediate yet subtle—lingering glances, tightened expressions, and a quiet frustration that he struggles to mask. The jealousy creeping into his demeanor is not loud or dramatic; it’s the kind that reveals unspoken feelings he has never fully acknowledged.
Do-ha isn’t angry at Ha-gyeong—he’s shaken by the realization that he might lose the one person who has always mattered to him. His jealousy becomes a window into his conflicted heart, showing both his longing and his regret for never expressing himself clearly. The drama beautifully captures this emotional shift, making viewers feel the weight of Do-ha’s internal struggle.
Ha-gyeong’s date isn’t just a romantic development—it serves as a catalyst for character growth. For Ha-gyeong, it symbolizes independence and the courage to embrace new possibilities. For Baek Do-ha, it forces a confrontation with his deepest emotions, pushing him to decide whether he will continue hiding behind silence or finally take a step toward honesty.
This jealousy arc adds rich emotional texture to the story. The tension between the characters intensifies, their choices become more meaningful, and the love triangle gains a new depth. The drama skillfully uses this storyline to highlight the complexity of love—how it can be calm, painful, and transformative all at once.
The moment Song Ha-gyeong chooses to go on a date marks a significant shift in The Last Summer. It challenges Baek Do-ha’s emotional detachment and redefines the relationships at the heart of the story. Through subtle performances and thoughtful writing, the drama captures the bittersweet reality of love, jealousy, and the fear of losing someone before you ever truly had them.
This scene doesn’t just move the plot forward—it deepens the emotional core of the series, setting the stage for even more compelling developments ahead.
