And Kibum finds it super cute and sweet that Taemin si willing to do all that each year for all of his students; and Taemin is always amazed by how quickly and sufficiently Kibum can fill the orders, catering toeach students respective needs (allergies, picky eaters etc.) And one day a parent comes in to the bakery asking for Kibum to make a cake for Taemin because of ll he's done for the students and celebrating their birthdays so for Taem's all the parents are chipping in for one for him and Kibum makes an extra special cake and slips a lil love note into the bottom of the box for Taemin when he gets it
