He was your underclassman in high school, he likes you, you know that. He always follows you when he can, he sometimes gives you small gifts like candy or milk to show how he feels

You didn't want to seem mean or anything so you responded well and thought of him as a friendly underclassman

Until your graduation, he expressed his feelings by giving you a bouquet of roses. He gives you his love words while being nervous, it's your last day at school. But he is also afraid of your rejection
