The promise I made during Spring

16 years old Elliot Robinson is just your everyday high schooler, born in an average family; living an average life. On his 16th spring, he met his old friend Blanc Ashton. They first met when they were 7 in elementary school; one day, Blanc suddenly moved away to another town after her parent death. After reuniting with his childhood friend, he noticed that something is different about her. Blanc, can't seem to smile or show happiness properly anymore, she forgotten what is "joy". That is when Elliot vowed to her that he'll help her remember what it's like to be happy and help her receive her "last gift" from her mother. However, making a promise is easy, but the action to fulfill it is the contrary.
