What Could Be Improved
1.Pacing in the Middle Episodes

2. Supporting Characters' Depth
Some secondary characters, though intriguing, could have been more fleshed out. Their arcs feel slightly underdeveloped compared to the leads.

Overall When the phone rings is a captivating blend of romance, suspense, and emotional depth, set against the backdrop of a mystery that keeps you hooked from the first moment. Adapted from a popular web novel, the show seamlessly weaves together the intricacies of human relationships with a thriller's pulse-pounding tension.
