HIStory2: Crossing the Line

Both shows are BL and have a main couple that meet in the beginning and slowly start to fall for each other. Both couples experience some obstacles that they need to overcome in order for them to be happy together. If you thought Right or wrong had good couple chemistry, just wait until you meet the main Boundry Crossing couple.

In both the shows, the plot is good with good actors and character development.

In terms of the leads dynamics and the premise (school, sports) I think these two are very similar to each other.

Also, both tug at heartstrings.

Another simple, lighthearted school BL centered around finding and accepting your feelings. They both have similar pacing, and the relationship dynamic is also similar: one entertainingly honest and caring character - paired with a more cold and quiet athlete.

"I'll Turn Back This Time" and a side bl couple in "HIStory2: Crossing the Line" are alike with stepbrothers brought together by their parents' remarriage. It started with a one-sided love and eventually turned into love for one another.

Entertaining big families that come close to heart.
The way both dramas deal with family-only dynamics is peaceful.
Full of comedy.
Heart-filling romances.
Double in-law couples.

There are no similarities plot wise, but if you are looking for another BL where the characters play sports, in this case volleyball, then Crossing the Line is an obvious suggestion.

Romance, sports BL.
Steamy kisses.
Cohabitation.
Great chemistry between leads.
Supportive, green-flag male leads.
