Doting seme x tsundere uke. Childhood friends Chiaki and Kazuma have been dating for a long time, but are not able to clearly express themselves. After moving to Tokyo and spending time apart, these lovers experience a longing that makes their time alone with each other even more

They are cute.
As they played together, they grew closer and closer until... things started getting hot, heavy, and sexy. They are not yet dating, nor have they had penetrative sex... but the two are most certainly getting down and dirty at every chance they can!

From skimming the highlighted panels I think I can confidently say, the cute crybaby blonde is the seme

About to now
The romantic comedy follows the everyday life of an extremely tsundere (initially aloof and abrasive, but later kind-hearted) boy named Atsuhiro "Akkun" Kagari and his girlfriend Non "Nontan" Katagiri. Akkun's behavior is harsh towards Nontan with verbal abuse and neglect, but he actually is head-over-heels for her and habitually acts like a stalker by tailing her or eavesdropping. Nontan is oblivious to Akkun's stalker ways, and thinks his actions are cute.
