Unfortunately they're still teens so these bouts of embarrassment are plentiful. But maybe after some time they'll relax and things will go by more smoothly.
... oh who am I kidding? Their crazy embarrassment is what makes these comics so funny!
Gouda is hesitant because he sees Kamine as a really well-behaved girl, so he just sit there and let Kamine lead their relationship, but Kamine is actually holding back so much as well, so both of them seems like they're holding back themselves to each other, while in reality they just kinda wanted to do things lovers usually do. You know, surprise kisses and stuff.
But yeah, this here is kinda awkward.
Ah... sorry about that...I went cough during my first kiss... I went cough during my first kiss...Do you want to try again?The end....and I wasn't even ready for it.Just now... that... was my first time...Uuuuuu!!
