I wonder if romance could ever be considered a tag in hentai. Story: For the first three episodes, each one focuses on an individual girl at a sort of winter lodge/mansion and the last episode has each girl have their own sex scene. From warming up during a winter storm to coming home for Valentines Day to visiting your home town after so long, each girl presents a different scenario for an intimate moment. The story for each girl is quite lovely, with my personal favorite being Mizuki from the first episode. The idea of being inside a nice, cozy home during a winter storm is byfar one of the most romantic scenarios a couple could have together. It seems a bit repetitive that each girl is placed in similar situations for a winter lodge, but the different scenarios that take place far make up for the repetitive nature. The only issue I have would be that the main male character is the same one for each girl, making this seem a bit off putting. In conclusion, this seems like such a sweet story to watch, especially if you are warming up on a cold night or even, dare I say, with your partner. 3.5/5

Music: there isn't much music used, even atmospheric, which I actually find to be more appropriate for the story and become more appealing. Music if often used in hentai to make it more erotic and arousing for the viewer, but no music added at certain points made it a bit more enjoyable due to its sense of realism, as ironic as that is. The other great thing about this hentai is the ending song, which is one of my favorite songs I have heard and learned. Certain scenes without music probably could've been better with music, but they are still good without it. 3.8/5

Animation: I wouldn't say the animation was bad, but it possibly could've been a bit better. The design and shading used for characters from lighting to the environments to the sex scenes were quite enjoyable, and there were hardly, if any, repetitive scenes used. In fact, the animation seemed to fit the hentai very well, but I'm certain it could've been even better. 4/5

True to genre: Vanilla is by far the most defined way to describe this hentai. As for the other genres, it is a bit questionable. Being four episodes, some of these genres were limited to certain girls, such as virgin for episode 3 and bondage in episode 4 for Mizuki only. Being different genres for each girl does add variety as each girl is different in kinks and figure, so despite there being a few genres limited to only certain girls, I feel that was best. 3.7/5

Eroticism: I found no arousal when watching this hentai, but that doesn't take away from how erotic it is for a couple. Being together to keep each other warm, celebrating your first Valentine's Day together, or seeing each other after so long, these moments are so precious and can be so intimate as memories. This did spark some personal fantasies I would love to have should I ever have a partner. I would say it definitely has a nice sense of arousal, not of being erotic, but of the passion that come from a couple together. 5/5

Concluding my review: Amakano is, personally for me, one of my favorite vanilla hentai to watch, because of its reminder to me of how I long for the moments I can share with a partner of my own. Despite it's flaws and not being a perfect score in a logical sense, this hentai will stand as perfect for me in its emotional sense.
