Heart Signal Season 2 (2019)

It's basically both a dating show where the main hosts are watching the house mates going through love. Heart Signal have 4 boys and 4 girls while on the other hand Love Timing have 4 girls and 5 boys. So while the housemates are in it to find love, it's up to the panelists to guess who will end up with whom.

This is a korean dating show that shows former couples living together, while none of the other couples know who the other exes are. These two shows are similar in the way they show romance in the daily life, but EXchange got a little different concept.

eight strangers are forced to live together while panelists with various experiences in dating and love look on from afar.

Same concept and structure, but have different panelists and people. Heart Signal 2 is the prequel to this season's (heart Signal 4).
