intriguing synonyms

It is a fun and exciting story revolving around two strangers who bumps into each other. Riya Verma is a young, sweet and helpful doctor, but she is hiding something from everyone... even her parents. She comes to another city to do her internship so that she can get away from her problems. She tries to hide behind her fake exterior. Till one day... Parth is a very hardworking Doctor. Dr Parth comes to her place all of a sudden and sees her being her normal self. He gets intrigued by her. He also sees her getting flabbergasted/terrified when her phone starts buzzing. He tries to find out the truth. So sit back and buckle up for this Joy ride they are single but not too ready to mingle in the most obvious way which makes their unassuming icebreaking movements watchable, like eavesdropping on a cute encounter, blushing with them, wincing at the little misgivings.
