This is what we call wholesome hentai. The two episodes are unrelated unfortunately.
Sure, the first seven minutes are pretty generic but after that, the new character that is introduced, makes the main character and her dynamic genuine and believable. Their scenes together was very wholesome and made me enjoy it more as it actually made me more emotional than the average hentai.
So action takes place very quick, not as wholesome, but intriguing. Same as the first episode though where the first half is not wholesome, at all, but the second half has way more dynamic with a better second half.
I recommend this if you want culture as well as a interesting emotional impact. Watch with discretion.
