Barry
Barry is a helpless romantic so he'll try his best to find the best restaurant in town, get himself all fancied up for you, he'll probably surprise you with a boatload of flowers but all he's tryna do is to make you happy.

Cisco
Cisco is a simple yet sweet guy so he'll invite you to his place so you guys can watch "the princess bride" while he makes both of you guys some popcorn, he's not gonna go all out like other guys but as long as he's trying him best to make you happy that's all that matters to you and that's why you love him.

Wally
Wally will invite you to come watch him drag race, he calls you his lucky charm because everytime you're there he always wins the races, then after the race he'll take you out to go see a movie, Wally loves you with all his heart and would do anything to make you smile.

Harrison wells
You and Harrison rarely go on dates because he's always busy with work but when you do it's usually a surprise, he'll take you out on a picnic on the beach and he go on a ramble about his ideas for improvement for star labs, he'll turn to you and ask him why you're looking at him like that and you'll say "because I love you" and replies with a smile "I love you too Y/N"
