Omfg I really cried! Istg! Not really a fan of kouhaixsenpai and unrequited love tropes but chapter 5 was it for me! Idk the desperatiin, the words conveyed, the emotions made my eyes bawl!
This is just my take: I think uke returned the pen because that pen is the the seme/relationship when they started dating. Seme said it was a known and expensive brand but it was so sudden so he was not able to have it engraved. It's like it's just giving appearances, just bec it is his bday he will give something expensive but it has no meaning to it because it was sudden he never took time to think about it that's why there is no label (engravement). It has no meaning that it is extra special. Meanwhile the keychain, it was the past seme, that uke cant let go. It symbolizes the person he admired and fell madly in love. That's why he wants to hang in to it. ong im rambling coz im cryung
