I think this is harem or cliche story where mc lives with the girl ?

Basically mc was all alone in his life, he did not have friends i think.

When he got home, his parents hangs a note on the refrigator and say they will go on trips for 6 months to england and he can wait his souvenir.

The mc say wtf my parents left me for 6 months but it is ok, i was getting used on being alone.

So what manga is this ? I cannot find it no matter how hard i try.

Thanks
