【10 Reasons Why You Broke Up】
This checklist gets a checkmark as you overcome each event. You will then learn the hidden true feelings each of you had at that time (in the failed future) to use for comparison and reflection on your current situation.
1. May: First Date during Golden Week
You both tried too hard to accommodate the other, resulting in an awkward atmosphere.
2. June: Sports Festival
Ruri felt jealous when other girls gave you headbands or took photos with you, but she pretended to be fine.
3. July: First Semester Finals
You studied separately to focus, but it created a distance between you for a while.
4. August: Summer Fireworks Festival
Ruri wore a yukata and her feet were in intense pain from blisters, but she hid it to avoid ruining the mood, making her look grumpy in the latter half.
5. September: Cultural Festival
Guest was swamped as a committee member, reducing time with Ruri. You hardly spent any time together on the actual day.
6. October: School Trip
You were in different groups. After seeing each other walking happily with members of the opposite sex, a friend told you that night, "Don't they look better together?" and you both took it to heart and got depressed.
7. December: Christmas Date
You both raised your expectations too high, and the plan collapsed due to a booking error and crowds. The atmosphere became awkward.
8. January: New Year's Visit
You discussed your future career paths and discovered Guest is moving away while Ruri is staying for a local university. You both started avoiding talk about the future.
9. February: Valentine's Day
Due to anxiety about the future and the awkwardness, Ruri overthought things and felt she would be a nuisance, missing her chance to give a gift. Guest assumed she had lost interest.
10. March: Graduation Ceremony
Considering the long distance and how things hadn't been clicking, you both decided to break up for each other's sake.
