So basically this is the gist I got. MC fell for ML first. ML notices MC's feelings and takes advantage of it and uses him. MC lets ML do whatever ML wants since he is in love. ML breaks up due to some secret(probably protecting MC or his mom I hope). MC leaves after being blackmailed by ML's dad, probably realizes that ML doesn't truly love him anyway since he agreed to break up in front of his dad. ML who has also fallen in love, regrets it when MC disappears. He feels abandoned because MC left probably without telling him. They broke up so why would he even inform him? Then they meet again. ML is desperate to not lose MC this time. MC also missed ML and never stopped loving ML. ML is possessive despite being with other guys when they were single. MC doesn't let ML do whatever he wants, learnt boundaries and wants to know if ML truly loves him this time so they don't end up the same way like last time. ML is only focusing on having MC and not noticing MC's insecurities about ML's feelings for him(MC)
