Heesu in Class 2 Episodes 1 and 2 Recap: A Triangle of Hidden Feelings
The opening episodes introduce a love triangle filled with tension and unspoken words. Hee-su secretly adores his neighbor and best friend, Chan-young, a popular boy who receives constant love confessions from girls but often struggles to reject them. Despite offering dating advice to others, Hee-su has never mustered the courage to admit his feelings to Chan-young or anyone else.
Their mutual friends often tease them about their close relationship, leading Hee-su to feel frustrated and conflicted about his feelings. Following a recent move from Hee-su’s neighbor, Seung-won now inhabits the next apartment. The stoic, reserved class president, Seung-won, becomes an intriguing addition to this close-knit dynamic.
In an emotional rooftop conversation, Hee-su comforts Chan-young after another breakup, all while suppressing his own feelings. A moment of surprise occurs when Hee-su catches Seung-won observing him from his window, only for Seung-won to quickly retreat, leaving Hee-su curious and confused.
The next day, Hee-su discovers a box of his favorite carrot juice mysteriously placed on his desk. Teased by his friends as a sign of a secret admirer, he notices Seung-won’s curious gaze that momentarily falters when they lock eyes. A collective wish to join the AV club leads Hee-su to express a desire to start an astronomy club, yet his request is denied.
When Seung-won brusquely instructs Hee-su to tidy his desk, their friends speculate about a supposed conflict between them. Chan-young jokes about Hee-su’s singing habits, further complicating Hee-su’s emotions. At the bus stop, he ruminates over the carrot juice mystery as Seung-won stands nearby, creating an unspoken tension between them. Hee-su ultimately distances himself, leaving Seung-won watching him from the bus window.

As the school day progresses, Hee-su once again finds a carton of carrot juice in his locker. His friends are playful in their denials of leaving the drink, igniting his intrigue. Seung-won later suggests Hee-su should join the counseling club—an unexpected offer that Hee-su accepts.
During his first encounter with the counseling club, he’s shocked to discover Seung-won at the helm as club president. Their dynamic shifts as Seung-won’s cold disposition dampens Hee-su’s initial enthusiasm. While reading submissions on the dashboard, Hee-su reflects on Chan-young’s previous acts of kindness, creating a juxtaposition against his growing uncertainty about his own feelings.
A peer who he had previously advised reveals her heartbreak over a crush who already has a girlfriend. Her story inspires Hee-su to finally consider confessing to Chan-young, bolstered by his sisters’ encouragement to take a chance. Brimming with determination, Hee-su races to the roller-skating rink where Chan-young is, only to be interrupted by Seung-won at a crucial moment.
Episode two resumes the tension directly from where episode one ends, with Seung-won nervously blurting an invitation to a seminar. Unbeknownst to Hee-su, whose emotions swing from heartache to anticipation, the situation becomes increasingly convoluted when Chan-young shows off a couple ring from Ji-yu, deflating Hee-su’s fleeting hopes.
The intrigue deepens as Hee-su encounters another box of carrot juice, igniting his curiosity once more. When he confronts Seung-won during the seminar, he learns that he is the club’s sole new member, further elevating his anxiety and embarrassment as he contemplates the dating advice he would give to an anonymous admirer.
Meanwhile, a chance meeting with a girl leaving behind a gift for a friend adds to his confusion regarding the carrot juice situation. Their shared moment watching the supermoon leads to deeper conversations about their families, which allows them to foster a greater connection.

Subsequent events lead to escalating misunderstandings as Seung-won fumbles with his invitation to a concert, clashing with Hee-su’s obliviousness to the brewing tension and misunderstanding surrounding their feelings. This culminates in a heartfelt conversation filled with potential life lessons entwined with rising emotions and a longing for connection.
In a twist of fate, Hee-su’s inquisitive nature leads him to another online post, hinting that someone has noticed his counseling talents. However, when his assumptions about Seung-woo’s interest surface, the façade begins to stir and challenge the dynamics of their friendship.
The final scenes of episode two set the stage for a potential turning point as Hee-su seeks to redefine his feelings and relationships. The next episodes, airing on April 4 and 5, promise to deepen the exploration of these friendships and hidden emotions.
Fans can look forward to new developments as each character embarks on a journey of self-discovery while navigating the complexities of growing relationships in an ever-evolving high school landscape.
