Last Summer Episode 4 Recap

The episode opens with Do-ha asking his father to sign over the property to him so that Ha-gyeong has to fight with him instead of his father for the property. Either way, he came prepared to do whatever he could for Ha-gyeong as he thinks back to 2 years ago, when she confronted him with the news that Do-young died a year prior and Do-ha was pretending to be Do-young for Ha-gyeong. In the present, he promises to stay here with her and face her wrath rather than live in regret for his entire life.

The next morning, however, Ha-gyeong is nowhere to be found. Do-ha realises that she has left the Peanut House and even tries to leave her job, but finds that particularly difficult. The task gets infinitely more problematic when Do-ha uses the mayor to make her stay back, and she has no option but to keep working with Do-ha. Frustrated and annoyed, Ha-gyeong recruits Patan High School’s alma mater to put a stop to the Observatory plans.

However, in a surprising twist, Do-ha wins everyone over easily, leaving her annoyed, but there are several old people who refuse to relent. Thankfully, Do-ha has a trick up his sleeve that immediately brings all of the men on his side. In the end, it’s Ha-gyeong who wins everyone over in a surprising twist, and Do-ha later questions her about wanting to be away from him so badly. He later gives her an explanation as to why he pretended to be Do-young, telling her that it came out of a desperate hope that he’s somehow alive after he went missing.

In the end, the two have another misunderstanding and Ha-gyeong leaves once more with a heavy heart. The next morning, Ha-gyeong meets Soo-hyeok and agrees to transfer the house to Do-ha, leaving him shocked. He questions why the sudden shift, and she confesses that she wants to live without him, blaming him and moving on from this ordeal, unwilling to play mind games with him anymore.

As the possibility of Ha-gyeong truly leaving becomes a reality, Do-ha thinks back to the past and his interactions with Ha-gyeong. He desperately tries to get her to stay till the end of the project and implores her to stay till August 31st, and she promises to think about it. In a surprising development, Ha-gyeong and Soo-hyeok spend some fun time together after bumping into each other at a bar in Seoul.

Their night is cut short when Do-ha asks her to come to the Peanut House because of a blackout, and the two eventually play with each other like old times. In the end, she agrees to stay till the completion date, and he gets a renewed sense of enthusiasm to change her mind about him. We see here that he caused the blackout to lure her back and change her mind about the entire thing.

Last Summer Episode 4 Review

Okay, till the last episode, I was sort of annoyed with Ha-gyeong’s constant negativity, and now I am extremely annoyed and a bit concerned with Do-ha’s creepy obsession with her. I mean, I get wanting the best of her, but when someone tells you no, you need to listen to it instead of putting your own wants and needs above their own. It seems concerning and selfish, and I am having a hard time finding it cute or caring in any way.
