Timeskips.........3 months pass
In these 3 months, the bond between Alex and Luna became unbreakable and they decided to tell Levi about this.
Today is Sunday and Alex came to home and all 3 gathered in the living room. Levi was a bit shocked because Luna sat beside Alex. Now both Alex and Luna said about the relationship between them to Levi at first Levi was silent and then spoke "If you ever break my sister's heart I'll break your bones".By hearing this statement Alex and Luna were happy because Levi accepted their relationship. After this day their relationship became public and many girls were jealous of Luna but Luna did not give a shit about them and was happy with Alex.
Like this, another 6 months pass and today is graduation day of Alex. After the graduation ceremony, Alex proposes to Luna and she accepts the proposal. They decided to get married after Luna's graduation. The next day they wanted to visit Alex's parents and Luna is pretty stressed out about this.
But to her relief, Alex's parents were very friendly and accepted Luna wholeheartedly and she felt like her family is complete.
After graduation, Alex took over his father's company and became the CEO while Luna is in the final year of high school. They both always tried to meet whenever possible but due to their tight schedule, it was not possible to meet often.
