How to Spot a Red Flag

Cha, a spunky coffee shop owner, finds solace in her online friend Matt whom she has yet to meet in person. However, everything changes when she finally comes face-to-face with the guy she's currently in the talking stage with.

Cha crosses paths with Matt while uncovering the secret behind a trending coffee mix. Matt, on the other hand, discovers that someone close to him is the catfish who got him canceled online.

Matt apologizes to Cha. However, reminded of how he owes JR his life, a guilt-ridden Matt hesitates to tell Cha the truth and instead makes a deal with his friend.

JR comes to Matt's rescue after Cha asked the latter out on a surf date. However, the barista considers ditching the plan when Ime disapproves of her action.

Matt ends up enjoying his surf date with Cha. An untoward incident brings them closer, but those around them seem unhappy about it. Later, Cha makes a realization.

Cha's suspicions about Matt grow stronger as they become text mates while recovering from their sprains. To confirm her hunch, the barista pays her friend a surprise visit, only to lead to more confusion.

Cha finally confirms that the person standing before her is not the same Matt she met online. After a heartfelt talk with Marian, Matt goes out of his way to find Cha and confess.

Matt finds it difficult to come clean to Cha as they spend more time together at the coffee farm. However, a sudden request will bring them back to square one.

Refusing to ruin the happy moment he shares with Cha, Matt once again decides to postpone his confession and instead tries to boost JR's image with her. However, to Matt's surprise and confusion, Cha agrees to meet JR and go on a date with him.

Matt is forced to do the right thing when JR fails to come clean to Cha, only to hurt the barista's feelings unintentionally. Meanwhile, Marian discovers an anomaly under JR's watch and reports it to Leandro.

Cha struggles to accept that she is catching feelings for the real Matt, despite the deceit. Despite doing the right thing, guilt weighs on Matt for hurting two of the most important people in his life.

JR apologizes to Cha and learns that Ayat Blends is about to close down. While JR plans to take advantage of Cha's dilemma to win her over, Matt finds a thoughtful way to help her and the displaced workers.

Despite her initial rejection, Cha decides to accept the job offer at Legacy Cafe for the sake of her team. Matt tries to be professional with Cha on her first day, while Marian reunites with Vivian after receiving a task from Leandro.

Despite Matt's effort to clear the air between them, Cha remains reluctant as she becomes determined to fight her growing feelings for him. Meanwhile, JR seizes an opportunity to get closer to Cha, causing Matt to seethe with jealousy.

JR finds a new opportunity to spend time alone with Cha. This time, Matt refuses to let them be, even going so far as to see JR flirting with the girl he likes.

With her parents’ support, Cha grows determined to revive Ayat Blends Café. Matt confesses his true feelings for Cha to JR and finally decides to pursue her. Unwilling to back down, JR steps up his game—both at work and in winning Cha’s heart.

When Cha loses her precious necklace, Matt and JR both rush to help her find it, each with their own approach to winning her favor. While JR spends more time with Cha at work, Matt focuses on making amends with Cha’s parents.

Seeing JR feeling down after a tense confrontation with his father, Cha steps in as a friend. Upon learning of JR's dilemma, Matt, without hesitation, rushes to his aid, which leads Cha to a new lead in the scam that started it all.

JR takes Cha to the beach to keep her from going to the precinct. A surfing match breaks out when Ime spots Cha and JR together and orders Matt to separate them.

The rivalry between Matt and JR intensifies as they ramp up their efforts to win Cha's favor. Despite the new developments in the scam case, Cha finds little cause for celebration, caught between two good friends now at odds because of her.
