HIStory2: Crossing the Line (2018)

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 recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

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.
