The premise of "Hen" a.k.a. "Strange Love" is this: A very large-breasted girl.
That's about it.
The two episodes I saw weren't very interesting. The girl models as a way to support herself, since she lives alone, but also attends a university which forbids its students to work. To disguise herself, she wears tinted contact lenses. One of her professors manages to recognize her in a commercial, despite this awesome camouflage, by her breasts. Face it, there aren't that many ZZZ-cup women walking around. He blackmails her and she agrees to "stay over" at his place, with predictable results.
The second episode brings up that old standby guaranteed to perk the interest of any hormonally-overdriven young man: lesbianism. There's a new girl at the university who awakens those special feelings in our heroine. Her boyfriend isn't all that happy about it, though.
Each episode is overlong by at least 15 minutes, skimping on both the "sex" and the "comedy". There is a decent amount of animated nudity, if that's your thing, but it isn't as explicit as it could (and probably should) be. There was only one moment that made me laugh, and nothing that titillated me (forgive the pun). About the only recommending factor I can think of is that this is "clean", not full of phallic tentacles violently molesting helpless schoolgirls.
