My step Sister Is Misbehaving

Hello everyone, I hope you all have a Nice Day, because I do enjoy my day playing football match, even though they win us with 5 : 2...

My step sister has a boyfriend who writes her love letter,have complained Many times if she will change, but not yet.

She is learning computer in another village and always comes back home late. A journey of 30mins back from her training center will take her close to two hours. And when I do investigation while she comes back late every day,I then notice she always branch the boy house before coming back home.

I am not always home because of my work. After the numerous complaint from my mum I decided to check her school bag and found four letters from a guy.

All the love letter was directly from the guy she normally visit when coming back from are computer training . I will be showing it my dad, but he don't normally say anything about it . Her mother was good to me even though we're not staying together, hence i we return the favor by treating her well . She just finished secondary school and will soon pick jamb form to further her education,but I'm afraid how she will become when she have a the freedom, when she get admission. I'm just afraid for her not to end up with pregnancy.

Hope to receive good comment on how or what way I can talk to her for her to understand the good thing I'm trying to do for her ...

Thanks. You all for reading and wish you guys happy Sunday in advance

I'm just afraid popsi might sent her packing.
