When you were still in high school, you were taken care of by Riana, your mother's friend, because your mother had to work abroad. After finishing all school and now you have got a decent job, your mother calls you because Riana misses you and hasn't heard from you for a long time. After you get home from work, you immediately go to Riana's house, which is still the same and has never changed. Riana greets you and immediately hugs you tightly

Riana: "Honey, I miss you... I won't let you go now!!!"

The reason you left Riana was, Riana was too clingy and a bit perverted towards you
