A sudden visitor, Kaoru, arrives at Mitsuya’s home. Upon seeing him, Mitsuya becomes visibly shaken and demands he leave. Seeing this emotional side of Mitsuya for the first time, Tomoya's mind races with assumptions. He later learns from Shige that Mitsuya and Kaoru were lovers ten years ago. Feeling inadequate compared to the sophisticated Kaoru, Tomoya’s anxiety spikes—but he makes a bold move to express his own feelings. Meanwhile, Kaoru makes a second visit to Mitsuya. What’s behind this “reunion after ten years”?

Tomoya attends Kaoru’s solo photo exhibition and overhears that Mitsuya has agreed to go to Paris. When they meet again at the event, Tomoya leaves without saying much, stung by the news. Wanting to move on, Tomoya submits a transfer request. During one final visit to pick up a manuscript, he asks Mitsuya to cook together—just once. Touched by the request, Mitsuya suggests a special “celebratory date” for the two of them.

Transferred to a sports magazine, Tomoya throws himself into his work. Meanwhile, Mitsuya maintains his usual busy routine of writing and livestreaming cooking content. One day, he comes home to find his beloved dog, Frito, collapsed and vomiting. Distraught by the possible loss of his only family, Mitsuya instinctively reaches out to someone... but who?

Tomoya Ishida, a young editor, struggles to fit in at a women’s magazine. One day, he’s assigned to fill in for a senior editor and becomes the new contact for Ayumu Mitsuya, a popular culinary expert frequently seen on TV and in magazines. Nervous to the point of collapse during his first visit, Tomoya is quickly won over by Mitsuya’s cooking. As he’s drawn in by Mitsuya’s gentle demeanor and occasional charm, Tomoya finds himself falling for him...

Tomoya’s jealousy flares when a handsome rival editor, Fujishima, enters the scene. Out of stubbornness, Tomoya refuses Mitsuya’s offer to cook for him. Later, they visit Mitsuya’s favorite spot, a restaurant run by Shige, where Tomoya's past triumphs and setbacks come to light. As they part, Mitsuya stops him, saying, “There’s something only you can do.” Just as their bond starts to deepen, a mysterious man suddenly appears, claiming Mitsuya as his boyfriend...!?

“I think I’m in love with you…” Tomoya’s unexpected confession leaves Mitsuya speechless. Things become even more complicated when Tomoya’s magazine arranges a dialogue between Mitsuya and his ex, Kaoru. Tomoya must now deal with his own feelings of shame and awkwardness after confessing to his client—while also confronting Kaoru. During the interview, Kaoru finally reveals why he returned to Japan: “Come back to Paris with me.” What will Mitsuya decide in the face of this ten-year-old love?

“Don’t come here again,” Mitsuya tells Tomoya after abruptly cutting ties. Their private date photo has gone viral on social media, creating a storm that leads to Tomoya taking a leave of absence from work. On the day of Mitsuya’s livestream, hateful comments flood in, and the studio is thrown into chaos. Meanwhile, Tomoya finds himself at a batting center, clinging to the hope that hitting a home run will help him forget the one he loves. Will these two hearts ever find harmony again?
