Mars Ochoco is your typical, hormonal high school student-socially awkward, insecure at times, and ma-drama to death. She isn't your popular girl either. The only thing that's going for her? She's charming. Ang problema nga lang, she doesn't know how to work her charm on the boys. Things take a sudden turn when she gets rejected by Zeke. Ang hindi niya alam, ang heartbreak na ito mismo ang magdadala sa kanya kay Mak Villareal, one of the most popular boys in school. He offers Mars an unconventional deal that she can't seem to refuse: tuturuan niya si Mars how to kiss to help her win her crush back! Mard eventually accepts Mark's proposal. After all, Mars has nothing to lose but everything to gain. At isa pa, wala naman halong feelings at attachment ang deal na ito 'di ba? Or wala nga ba talaga?
