No, they don't. In the last episode it appears that Aki is going to confess to Yuusei, but nothing happens.
No, there are no kisses in the show.
Yes he does, they are really into each other, it's apparent in episode 39 and onward in the subbed version.
Yuusei is 18.
Yuusei's parents lost their lives in the Zero Reverse Effect that resulted in a disastrous tectonic shift that split Domino City into two.
of coarse they will they are just friends now but you can so tell that yusei likes her. Martha teaes him for likeing her thay are just building up to it its a way two keep people watching it. If all they whant is two see them kiss then once they do then they will stop watching it.
Yu-Gi-Oh! 5D's seems to take place many years after Yu-Gi-Oh! GX. Yuusei and Yuugi probably aren't related.
Doctor Fudou, he was killed in the Zero Reverse incident.
There isn't a official date for Yuusei's birthday, yet.
They're the same age, because at the end of Yu-Gi-Oh! GX Judai is 18 years old an at the start of Yu-Gi-Oh! 5D's Yuusei is 18 years old.
No. Nobody does not kiss him.
