Love Class 3

A year after competing together on an idol survival show, Hyunjae debuts successfully while Sooan, eliminated before the finale, works behind the scenes as a studio staffer. Reunited unexpectedly at a fan meeting, the two are forced to confront lingering feelings and painful memories. Meanwhile, Jaemin, ruined by a stalking scandal, returns to college and crosses paths with someone new.

After unexpectedly reuniting with Sooan, Hyunjae becomes convinced he saw him working backstage at a fan meeting and starts searching for him. Meanwhile, Jaemin reconnects with his painful past while growing closer to the blunt yet mysterious Khun, whose expensive gift leads to misunderstandings, flirtation, and an unexpected proposition.

As Hyunjae rises to fame as an idol, Sooan faces setbacks with training failures, company troubles, and growing jealousy. Meanwhile, Jaemin helps Khun move into his new place, and the two end up bonding over a meal of black bean noodles.

Hyunjae and Sooan struggle to hide their feelings as they push each other away over a misunderstanding. Meanwhile, Jaemin is confused after getting drunk and growing unexpectedly close to Khun, only to be paired with him for a couple-themed class project. As emotions become harder to ignore, a mysterious phone call changes everything.

With PNJS and Unicorn Entertainment merging, Hyunjae unexpectedly reunites with Sooan, who acts like nothing happened between them. Meanwhile, Khun is revealed to be a famous musician and joins the company. Jaemin is shocked when Khun accuses him of approaching him with a hidden agenda.

Khun is a world-famous Thai musician, who was driven into retirement by invasive fans and constant scrutiny. After learning Jaemin is an idol trainee, Khun struggles to trust him. Meanwhile, Hyunjae competes with Hajun for Sooan's attention as debut evaluations approach.

After the debut team is announced, the crew is invited to a team dinner, where resentments over the merger and lineup selections erupt. Ricky insults Khun and implies he and Jaemin are involved, prompting Jaemin to shock everyone with an unexpected response.

Hyunjae takes care of a drunken Sooan after a gathering, and old feelings resurface, but Sooan continues to keep his distance. Meanwhile, a news article claiming that Khun will debut in Korea sparks tension between his Thai agency and PNJS Entertainment. Worried about him, Jaemin tries to find Khun and check on him.

Jaemin struggles with his feelings after seeing Khun and Stella together and is harshly criticized during dance practice for repeated mistakes. Sooan discovers that Hyunjae had secretly been cleaning and preparing the practice room for everyone.

Hyunjae and Sooan's dance video goes viral, prompting the company to push them as a duo and create more content together. Jaemin wakes up at Khun's place and finally talks to Stella.

Hyunjae and Sooan bond during filming. Jaemin struggles to confess to Khun, practicing and planning a heartfelt letter and surprise. Meanwhile, Khun continues to face obsessive fans and stalkers.

As the group prepares their debut song, Jaemin's reputation begins to recover after positive media coverage clears the stalking allegations. Meanwhile, Sooan and Hyunjae finally confront their misunderstanding about the missing texts.

Jaemin's scandal escalates as manipulated messages are released and Ilwoo's side threatens legal action. PNJS's CEO coldly decides to sacrifice him for the company's image. Jaemin believes he has nowhere left to go, until Khun stands by him.

Sooan is devastated when PNJS cancels the group's debut and shifts focus to Hyunjae's solo career. When Sooan confronts him, Hyunjae coldly insists their relationship was never more than business. Meanwhile, Jaemin finds refuge in Thailand with Khun, where they grow closer and Jaemin experiences a rare sense of safety and freedom away from the scandal.

Sooan worries about Hyunjae's disappearance. Hyunjae discovers how the company used his relationship with Sooan against him and realizes he must take back control of his own choices. Meanwhile, Jaemin and Khun begin a new life together after Khun ends his contract with PNJS.

Jaemin and Khun return to university, choosing to walk forward together. As Hyunjae exposes PNJS's manipulation and takes responsibility to protect Sooan, the truth behind the audition scandal is revealed.
