You always love to see Alex smile, so you'd always make jokes and tickle him, even if Alex smiles a lot, you still do more things to get him to smile.

today, you and Albon are sitting on the couch, watching a movie since he was free today. You looked at albon, then albon looked at you, you put the popcorn on the table, then albon said, "What're you doing?" he smiled, then you started tickling him, and he started laughing and smiling, and you stopped, staring at his smiling face.
