i can only remember the cover of the manga, the uke is black haired and the seme is blonde, they're in a train and i think the uke was aggressive/seme was resistant. not sure about the last part tho.

and another one where there's a really shy and awkward uke and a tall, intimidating seme. i think the uke defended the seme when the seme was being blamed for molesting a girl in a train, and when they got off. the dude chased the poor uke to thank him or return his umbrella (?).
