A Puppetry (2022)

Despite the modern vs. historical settings, both dramas have the same premise of the FL trapped in a time loop that ends with a fiery explosion before the day repeats again.

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

Both are mini dramas with the FL stuck in a day long time loop.
.............................................

Both are set within the world of a historically set manga and start with the FL dying and then traveling back in time. At some point in the story (start vs. near the end), the FL becomes stuck in a time loop of a day.

Both are mini dramas with a fictional historical setting (game vs. manga) with the FLs dying/reliving the same events repeatedly and trying to change them.

Both are short length historical dramas in which the FL is an entertainer of some kind (puppeteer vs. street magician). Both involve a mystery.

Both are mini dramas in which a real world person enters a story and falls in love. Both have almost identical endings.
