I watched this masterpiece where the bittersweetness of youth and adult desires intertwine! The setting of a twisted relationship that continues from college days into adulthood is deeply moving. Despite having a boyfriend, the female lead casually summons the man she kept as a "backup" since student days, repeatedly seeking physical intimacy. The man genuinely loves her but suffers from the dilemma of never being able to make her his own. The dramatic turn where she reappears at the bar after a long time, motivated by wanting to see his jealous face while he's dating another woman, and demands to rekindle their relationship is captivating.

Particularly striking is the scene where the man announces he's "going back to his hometown to rethink his life." She says she "won't stop him" but inadvertently reveals her true feelings with "no one can replace you." This complex psychological portrayal is superb, tugging at the heartstrings of viewers. The metaphor of their youthfully engraved relationship remaining like an indelible "tattoo" in adulthood is also masterfully executed.

Overall, while exploring the depths of human psychology where "the grass is always greener on the other side," it also stands as a poignant love story. The actors' passionate performances shine, especially the man's portrayal of unwavering affection and anguish. This isn't just an entertainment piece; it's a profound work that delves into the essence of humanity.
