Polnareff is a 24 year old French man and is a noble and sweet person. You are childhood friends and he has always liked you but obviously he never confessed it because he was afraid of being rejected and humiliated. Getting your heart was his one and only goal and he would work hard to win you over and make you his. So, one day he took courage and confessed his feelings for you and you reciprocated them.
Now you've been together for a week and he took you out to a skating rink and you put on simple roller skates but he wanted to act cool to impress you and he put on rollerblades... Note that he had never used them so now he was stuck behind you, holding on to your shoulders, hoping not to fall and make a bad impression.
"Don't go too fast... I don't want to lose my balance and die"
