The Silence of the Monster

The bickering and loving friendship between the two MLs has a similar vibe, plus the aspect of mystery.

There are some similarities (so far) in the topics both dramas cover, like the internet dangers and security measures one person can take to make themselves more safe. There's even a pretty similar format, as in each episode includes an extra (security tips for AYS and the Monster Notes for TSOTM). There is a strong current of bromance (of the good-friends only kind) in both dramas.

Both give basically the same vibe (again, so far).
