The fifth episode of the drama series "First Love DOGs" (TBS, Tuesdays at 10pm), starring actress Kaya Kiyohara, aired on July 29th.

Aiko (Kiyohara) and Soha were spending time together at Kai's (Ryo Narita) house. There were two large watermelons in the house, one of which had been partially cut up. Soha promised Aiko, "I just had a glass of watermelon juice here. I'll make some for you later. My special Soha watermelon juice is really delicious."

Kai was watching the two of them.

Kai, who was about to go for a walk, told Aiko, "It's just the two of you from now on. Although I may look like this, I have quite a keen sense, so I'm being careful. Please take care of me, Soha."

Feeling that Kai had misunderstood her and thought she had feelings for Soha, Aiko confessed, "My first love was Shirasaki (Kai).Right now, all I can think about is Shirasaki."

After seeing Aiko's confession to Kai, Soha sneaks off to another room. She is shown drinking two glasses of juice with a lonely look on her face.

On social media, the post became a hot topic, with comments such as "Soha, it's so sad," "The second watermelon juice Soha was holding was Aiko's, right? It's kind of sad," "Drinking watermelon juice by herself was really sad," and "Nainu is so cool. And it looks like she's getting better at Japanese."
