Just 'cause you do it all the time doesn't mean it's not serious.Your lips have to be sticking to his lips all the time like the North and South poles of 2 magnets...Nope! You got it wrong!Is kissing supposed to be treated so casually...?But...※ This is only Secchan's personal opinion.You have to be kissing 24/7.Sure, but mostly...Lots of normal stuff...?
