Both are mini dramas about the relationship between a human FL and an android ML who slowly begins learning emotions the more time he spends with her.

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

- same title
- exactly same concept with robot theme being a house keeping robot
- both have romance

Both are mini dramas about artificial intelligence and the relationship human(s) form with her or him. Both androids attend school pretending to be a human.

Both similar in how there is romance between one non-human and human. Although in IANAR the FL is pretending to be a robot.
