Episodes measured in minutes

Just Friend is built for short viewing. Its six episodes run between about six and eight minutes, with the first the longest at 8 minutes 2 seconds, so each installment fits into a break rather than an evening. The title is plain and conversational, and the numbering EP. 01/06 on every upload tells viewers from the start how many parts to expect. Every upload carries the Korean title 저스트 프렌드 beside the English one, and the label BL K-drama in the title marks the series for international viewers who search in English.

A weekly rhythm after a first upload

The first episode went online on Tuesday 8 September 2026, and the next three followed on Wednesdays, 16, 23 and 30 September. That steady cadence gives the series a weekly habit even though each part is brief, and it leaves the last two episodes still to come on the channel. Because the run is only six episodes long, the whole story is close to its end after four weeks, which makes it easy for new viewers to catch up.

Made for the platform it plays on

The drama is released openly on YouTube by the Rainbow channel, with subtitles on the episodes, so it can reach viewers outside Korea from the first upload. The channel presents itself as a home for original queer web dramas, and Just Friend follows that pattern as an original production rather than an adaptation. Members are offered an uncut extended version, which gives the open episodes a companion cut for those who want more.

The cast and credits

The two leads are Lee Jae Sung as Han I Jun and Ji Seung Jin as Kang Eun U. Behind the camera, the same person is credited as both director and editor, so the pacing of each short episode is set by a single hand.
