hello,

i am looking for a manga which has the story going like there is happy couple until the day the wifes sister visits them. The husband is madly in love with his wife but accidentally rapes the sister in law under the influence of alcohol i guess when she goes to find him coz he took long to reach home. next day when he wakes up he doesn't remember much about anything happening but the wifes sister remembers everything and she is traumatized. she goes then fooling around until one day she returns to her sisters place and the brother in law and sister in law again engages in physical contact and this keeps on going on and one day the wife sees this ....

flashback : this wife had a scary past for her sister to lead a good life and coz she had a debt she had to sleep with her old landlord ... she met her husband when he was serving during his compulsory army service and married him just coz her younger sister(back then was just a kid) felt happy around him and coz he was a good man .

i have vague memory about this manga but if anyone could tell me which one this is i would really appreciate it... it is ongoing as far as i know and the cover is like a man dressed in army clothes sitting on the floor and a woman stripping front of him i guess.

Thank you
